Question

Solve 7x-3y=14 for y​

Answer 1

Explanation:

● 7x-3y = 14

This a 1st degree equation with two variables.

● 7x-3y = 14

Substract 7x from both sides

● 7x-7x -3y = 14-7x

● -3y = 14-7x

Mulitply both sides by -1

● (-1)×(-3y) = (-1)×(14-7x)

● 3y = -14+7x

● 3y = 7x+14

Divide both sides by 3

● 3y/3 = (7x+14)/3

● y = (7/3)x + 14/3

There are infinite solutions for this equation. Keep replacing x with value and the output will change everytime.

Answer 2

y = - 14/3 +7x/3

Explanation:

The reason for my answer is because let us move the -3y so it is before the equal sign. Let us also move 7x to the other side but make it so 14 would be to the right side of the equal sign. Now, that would mean 7x would be after 14. Our equation is now -3y=14-7x. We need to divide both sides of the equation by -3. There, we just divided -3y by 3 which equals to y. 14 divided by -3 equals to -14/3. -7x divided by -3 would equal to +7x/3. Finally, we get the answer of y = - 14/3 +7x/3.
