How do you add 2x plus 3y equals 18 in 5x-y equals 11
x equals 19
answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4
19
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
2 + 2x = 18 2x = 18 - 2 2x = 16 x = 8
2x + 10 = 182x = 8x = 4
