Question

I have no idea how to do any of these so please explain I'm already struggling and school just started

1.

`5g + h = g`
solve for g
2.

`y = mx + b`
solve for m

3.

`3y + z = am - 4y`
solve for y

4.

`km + 5x = 6y`
solve for m

5.

`(3ax - n)/(5) = - 4`
solve for x

6.

`(by + 2)/(3) = c`
solve for y

7.

`at + b = ar - c`
solve for a

​

Answer 1

See below!

Explanation:

1. 5g + h = g

4g = -h

g =
`-(h)/(4)`

2. y = mx + b

y - b = mx

m =
`(y - b)/(x)`

3. 3y + z = am - 4y

7y = am - z

y =
`(am - z)/(7)`

4. km + 5x = 6y

km = 6y - 5x

m =
`(6y - 5x)/(k)`

5.
`(3ax - n)/(5) = -4`

3ax - n = -20

3ax = n - 20

x =
`(n-20)/(3a)`

6.
`(by+2)/(3)= c`

by + 2 = 3c

by = 3c - 2

y =
`(3c-2)/(b)`

7. at + b = ar - c

at - ar = -b - c

a(t - r) = -(b + c)

a =
`-(b+c)/(t-r)`
