8x-7 plus 2x equals 6 plus 5x plus 2?
x=6
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
DIE
(6, -4)
5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
x2 + 5x + 3 = 9 x2 + 5x - 6 = 0 (x + 6)(x - 1) = 0 x = -6 or x = 1
