4y + 4 = 3y - 5 y = -9
(4, 5)
5 + 3y = -4 First subtract 5 from both sides. 3y = -9 Then divide both sides by 3. y = -3
3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
2x-11
30 - 12 = 18
4y -5
3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8
3y+2y+4+1=80 5y+5=80 5y=80-5 5y=75 y=15
{-4,-5}
80 = 3y + 2y + 4 + 1 80 = 5y + 5 80 - 5 = 5y + 5 - 5 75 = 5y 75 / 5 = 5y / 5 15 = y
5*4+3*3 = 29
