x2 + 2x - 15 = (x - 3)(x + 5)
x = 2
x = -5
(-5, 2)
5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.
2x2 + 11x + 15 = (x + 3)(2x + 5).
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
Presumably, this is an equation in finding the value of x 3x+5/4 = -2x+15 3x+1.25 = -2x+15 3x+2x = 15-1.25 5x = 13.75 x = 2.75
2x+x-5 = 10 2x+x = 10+5 3x = 15 x = 5 and y = 0
2(5) + 3(5) = 10 + 15 = 25also 2x+3x=5x and 5(5)=25â–
13x + 15 = 11x - 5 2x = -20 x = -10
2x-5y+15=0 -5y=-2x-15 y=(2/5)x+3
