Question

Hi can you help me please?)

Answer 1

To solve for a variable, isolate that variable onto one side.

17.

Firstly, multiply both sides by 5/2:
`z+1=(5)/(2)y`

Next, subtract both sides by 1 and your answer will be
`z=(5)/(2)y-1`

18.

Firstly, divide both sides by g:
`h+(2)/(3)=(1)/(g)`

Next, subtract both sides by 2/3 and your answer will be:
`h=(1)/(g)-(2)/(3)`

19.

Firstly, foil a(n - 3):
`an-3a+8=bn`

Next, subtract an on both sides:
`-3a+8=bn-an`

Next, factor out n on the right side of the :
`-3a+8=(b-a)n`

Lastly, divide both sides by (b - a) and your answer will be:
`(-3a+8)/(b-a)=n`

Answer 2

solve by simplifying both sides of the equation then isolating the variable

z = -1 + 5y/2

Isolate the variably by dividing each side by factors that dont contain the variable

h = -2/3 + 1/g

Move all terms to the left side and set equal to zero, then st each factor equal to zero

n = 3a-8 / a-b

I hope this helps
