Question

Hi can you help me please?)

Answer 1

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

Answer 2

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

17.

Firstly, multiply both sides by 5/2: $z+1=\frac{5}{2}y$

Next, subtract both sides by 1 and your answer will be $z=\frac{5}{2}y-1$

18.

Firstly, divide both sides by g: $h+\frac{2}{3}=\frac{1}{g}$

Next, subtract both sides by 2/3 and your answer will be: $h=\frac{1}{g}-\frac{2}{3}$

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: $\frac{-3a+8}{b-a}=n$
