The solution set for a linear equation in two variables comprises an infinite number of ordered pairs, and these are defined by the equation that appears in the question!
x=-2
8x - 7 = 15 + 19xsubtract 19x from both sidesadd seven to both sides8x -19x = 15 +7-11x = 22divide both sides by -11x = -2
19x
x^2-19x+90 (x-9) (x-10)
6x2+19x+10 = (2x+5)(3x+2) Length = 2x+5 Width = 3x+2
x=-2
8x - 7 = 15 + 19xsubtract 19x from both sidesadd seven to both sides8x -19x = 15 +7-11x = 22divide both sides by -11x = -2
-171 = 19x so x = -9
19x = 437 x = 437 ÷ 19 x = 23
152
19x = 437 x = 437 ÷ 19 x = 23
19x = 114x = 114/19x = 66 x 19 = 114
5x + 5y = 19x = 3.8 - yory = 3.8 - x
19x
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
