7x-5y=-25
Subtract 7x from both sides of the equation.
-5y=-25-7x
Divide each term in -5y=-25-7x by -5.
-5y-5=-25-5+-7x-5
Cancel the common factor of -5.
Cancel the common factor.
-5y-5=-25-5+-7x-5
Divide y by 1.
y=-25-5+-7x-5
y=-25-5+-7x-5
Simplify each term.
Divide -25 by -5.
y=5+-7x-5
Dividing two negative values results in a positive value.
y=5+7×5
y=5+7×5
y=5+7×5
The given equation y=5+7×5 can not be written as y=kx2, so y doesn’t vary directly with x2.
