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

Respuesta :

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
7x - 10y = 30

move 7x ----- -7x
- 10y = 30 - 7x

divide -10

y = - 3 + 7/10x

now you have

y = 7/10x - 3
