5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
7x-5x=8 2x=8 x=4
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
5x+3=8 is a simple equation, and I can tell you off the top of my head the answer is 1. Here's how to work it: 5x+3=8 5x+3(-3)=8(-3) 5x=5 5x(/5)=5(/5) x=1
5x - 8 = yWhen y = 1,5x - 8 = 1Add 8 to each side of the equation:5x = 9Divide each side by 5:x = 9/5 = 1.8
5x+2y>8, y≤4 5x+2(4)>8 5x+8>8 5x>0 x>0
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
It is: 8-5x simplified
2X2+5x-12 4+5x-12 -8+5x 5x-8
if it is 5x + 8 = 23 then the answer is 3. if it is 5x - 8 = 23 then the answer is 31/5.
4x - 8 = 5x 1) Add 8 to both sides. 4x - 8 (+ 8) = 5x (+ 8) Becomes 4x = 5x + 8 2) Subtrate 5x from both sides. 4x (- 5x) = 8 Becomes -1x = 8 Reduced to -x = 8 3) Multiply both sides by -1. Becomes x = -8
5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
20x2 - 27x -8 20 * -8 is -160, and -32 and 5 add to -27 20x2 - 32x + 5x - 8 4x(5x-8) + 1(5x-8) (4x + 1)(5x-8)
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
It is 5x - 4
5x+(6-3x)+8=5x+6-3x+8=2x+14 2x + 14
