Question

the equation 7x-10y=30 is written in standard form. What is the first step when writing an equivalent equation which solves for y.

Answer 1

if you use the multiplication chart for 10 and 7 you the find the right numbers to subtract from to get 30

Answer 2

You solve for y so then u subtract the 7x from 30 to get 30-7x equals -10 since the -10 has a variable it means u divide by -10 to the subtracting equation to get-3+7/10
