Question

Y = 7x - 10 & y = -3

Answer 1

x=1

Explanation:

First, we can substitute -3 for y. So we get -3=7x-10

We then have to isolate the variable x by adding 10 to each side of the equation.

Then we have the equation 7=7x.

Finally, we divide both sides by 7.

We get the finally answer x=1 and y=-3.

Answer 2

x=7-13
