2x - y = 15 2x + 3y = -21 As you observe both equations (having different slopes), you see that the system is consistent, and it has only one solution.

X=7

Inconsistent linear equations in two variables.

x2 + 2x - 15 = (x - 3)(x + 5)

x=4

x = 2

2x + 8 + x = 2x + 15 simplify 2x to both sides since they have the same sign8 + x = 15 subtract 8 to both sidesx = 7

4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11

it equals 13X.

8x = 2x + 15 6x = 15 x = 15/6 = 2.5

x = -5

5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.

-7 +2x = x + 8 2x - x = 7 + 8 x = 15

(-5, 2)

(5,3)

8x+39 = 2x-15 6x = -54 x = -9

x=1

Y=15/(2c+2x)

2x + 15 = 8x + 43 -6x = 28 x = -6 / 28 = -3 / 14

2x2 + 11x + 15 = (x + 3)(2x + 5).

x over 4= 2x+3 over 15

4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.

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-5y+15=0 -5y=-2x-15 y=(2/5)x+3

What is the answer to 2x - 5x plus 6.3 equals -14.4?
