Question

I don't know how to find the indicated variable of equations like this or any equation in general

Answer 1

Solve for x (that is the indicated variable)

-8x + 10y = -30

-8x = -10y - 30

x = 1.25x + 3.75

Solve for y (that is the indicated variable

-8x + 10y = -30

10y = 8x - 30

y = 0.8x - 3
