-2x = y^5 or y^5 = -2x y = (-2x)^(1/5)
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
2(2x + 5)(2x - 5)
2x+5y=20 Solve for y -2x -2x 5y=20-2x 5 5 5 y=4-2x 5
Simplifying 4x + -5 = 2x + 7 Reorder the terms: -5 + 4x = 2x + 7 Solving -5 + 4x = 7 + 2x Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -5 + 4x + -2x = 7 + 2x + -2x Combine like terms: 4x + -2x = 2x -5 + 2x = 7 + 2x + -2x Combine like terms: 2x + -2x = 0 -5 + 2x = 7 + 0 -5 + 2x = 7 Add '5' to each side of the equation. -5 + 5 + 2x = 7 + 5 Combine like terms: -5 + 5 = 0 0 + 2x = 7 + 5 2x = 7 + 5 Combine like terms: 7 + 5 = 12 2x = 12 Divide each side by '2'. x = 6 (your answer)
-2x - 5
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x

12x + 5 - 2x =(12x - 2x) + 5 =10x + 5 =5 (2x + 1)
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
