Mathematics

Simplify 9 - 7x - 7x to 2 - 14x

2 - 14x = 4

Subtract 2 from both sides

-14x = 4 - 2

Simplify 4 - 2 to 2

-14x = 2

Divide both sides by -14

x = -2/14

Simplify 2/14 to 1/7

x = -1/7

To write in slope intercept form solve the equation for y:

4x + 3y =15

Subtract 4x from both sides:

3y = -4x +15

Now get Y by itself by divide all terms by 3:

y = -4/3x + 5
