-171 = 19x so x = -9
19x = 437 x = 437 ÷ 19 x = 23
152
19x = 437 x = 437 ÷ 19 x = 23

5x + 5y = 19x = 3.8 - yory = 3.8 - x
x^2-19x+90 (x-9) (x-10)
6x2+19x+10 = (2x+5)(3x+2) Length = 2x+5 Width = 3x+2
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33
-38-10x = 9x+19 -38-19 = 9x+10x -57 = 19x |: 19 -3 = x Therefore x equals -3
