Question

It’s literal equations and i really need help

Answer 1

Part 1)
`x=(g)/(c)`

Part 2)
`a=(1)/(3b)`

Part 3)
`a=(n+p)/(m)`

Part 4)
`x=g-y+c`

Part 5)
`x=(z)/(m-1)`

Part 6)
`a=(g+b)/(c)`

Part 7)
`b=(A)/(h)`

Part 8)
`W=(P)/(2)-L`

Part 9)
`d=2Q-c`

Part 10)
`a=(Q)/(3+5c)`

Part 11)
`N=(A))/(P-IR)`

Part 12)
`b=P-a-c`

Step-by-step explanation:

Part 1) we have

`g=xc`

solve for x

That means---> Isolate the variable x

Divide by c both sides

`(g)/(c)=(xc)/(c)`

simplify

`x=(g)/(c)`

Part 2) we have

`12ab=4`

solve for a

That means---> Isolate the variable a

Divide by 12b both sides

`(12ab)/(12b)=(4)/(12b)`

simplify

`a=(1)/(3b)`

Part 3) we have

`am=n+p`

solve for a

That means---> Isolate the variable a

Divide by m both sides

`(am)/(m)=(n+p)/(m)`

simplify

`a=(n+p)/(m)`

Part 4) we have

`g=x-c+y`

solve for x

That means---> Isolate the variable x

Subtract y both sides

`g-y=x-c+y-y`

`g-y=x-c`

Adds c both sides

`g-y+c=x-c+c`

`g-y+c=x`

rewrite

`x=g-y+c`

Part 5) we have

`xm=x+z`

solve for x

That means---> Isolate the variable x

Subtract x both sides

`xm-x=x+z-x`

`xm-x=z`

Factor x left side

`x(m-1)=z`

Divide by (m-1) both sides

`(x(m-1))/(m-1)=(z)/(m-1)`

`x=(z)/(m-1)`

Part 6) we have

`g=ca-b`

solve for a

That means---> Isolate the variable a

Adds b both sides

`g+b=ca-b+b`

`g+b=ca`

Divide by c both sides

`(g+b)/(c)=(ca)/(c)`

`a=(g+b)/(c)`

Part 7) we have

`A=bh`

solve for b

That means---> Isolate the variable b

Divide by h both sides

`(A)/(h)=(bh)/(h)`

simplify

`b=(A)/(h)`

Part 8) we have

`P=2L+2W`

solve for W

That means---> Isolate the variable W

Subtract 2L both sides

`P-2L=2L+2W-2L`

simplify

`P-2L=2W`

Divide by 2 both sides

`(P-2L)/(2)=(2W)/(2)`

simplify

`W=(P-2L)/(2)`

`W=(P)/(2)-L`

Part 9) we have

`Q=(c+d)/(2)`

solve for d

That means---> Isolate the variable d

Multiply by 2 both sides

`2Q=(2)(c+d)/(2)`

simplify

`2Q=c+d`

subtract c both sides

`2Q-c=c+d-c`

`2Q-c=d`

rewrite

`d=2Q-c`

Part 10) we have

`Q=3a+5ac`

solve for a

That means---> Isolate the variable a

Factor the variable a in the right side

`Q=a(3+5c)`

Divide by (3+5c) both sides

`(Q)/(3+5c)=(a(3+5c))/(3+5c)`

simplify

`a=(Q)/(3+5c)`

Part 11) we have

`I=(PN)/(RN+A)`

solve for N

That means---> Isolate the variable N

Multiply in cross

`I(RN+A)=PN`

Apply distributive property left side

`IRN+AI=PN`

subtract PN both sides

`IRN+AI-PN=PN-PN`

`IRN+AI-PN=0`

subtract AI both sides

`IRN+AI-PN-AI=-AI`

`IRN-PN=-AI`

Factor N left side

`N(IR-P)=-AI`

Divide by (IR-P) both sides

`(N(IR-P))/(IR-P)=-(A)/(IR-P)`

simplify

`N=-(A)/(IR-P)`

`N=(A)/(P-IR)`

Part 12) we have

`P=a+b+c`

solve for b

That means---> Isolate the variable b

subtract (a+c) both sides

`P-(a+c)=a+b+c-(a+c)`

simplify

`P-(a+c)=b`

rewrite

`b=P-a-c`
