Question

Can someone pls help me with 15 and 18 ?

Answer 1

x/5 - g = a Solve for x

x/5 = a + g Add g to both sides of the equation

x = 5(a + g) Multiply both sides of the equation by 5

g(h + 2/3) = 1 Solve for h

gh + 2/3g = 1 Distribute

gh = 1 - 2/3g Subtract 2/3g

h = 1/g - 2/3 Divide by g to isolate h

Hope that helps!

Answer 2

`\frac x 5 -g = a`

`\frac x 5= a + g`

`x = 5(a+g)`

---------------

`g(h + \frac 2 3 ) = 1`

`h + \frac 2 3 = \frac 1 g`

`h = \frac 1 g -\frac 2 3`
