Question and answer
If the second equation is multiplied by 4 and then the equations are added, the result is _____. x + 4y = 1 x - y = -3 5x = -11 3x = -13 5x = -13
If the second equation is multiplied by 4 and then the equations are added, the result is 5x = -11, x + 4y = 1 x - y = -3. x*4 - y*4 = -3*4; 4x - 4y = -12; x + 4x + 4y - 4y = -12 + 1; 5x = -11

If the second equation is multiplied by 4 and then the equations are added, the result is 5x = -11, x + 4y = 1 x - y = -3.
x*4 - y*4 = -3*4;
4x - 4y = -12;
x + 4x + 4y - 4y = -12 + 1;
5x = -11

(x + 8)(y + 3)
= x*y + 8*y + x*3 + 8*3
= xy + 8y + 3x + 24
