6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
2x - 5 = 15 2x = 20 x = 10
6x - 8 + 2x - 5 = 7 - 2x ?
2x+3y-5=0
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
x2 - 2x + 55 = 90x2 - 2x - 35 = 0(x+5)(x-7) = 0x = -5, 7
2x+3 = 7 2x = 7-3 2x = 4 x = 2
Solve for y: f(-5)=13+2x
2x - 5 = 15 2x = 20 x = 10
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)
210
If 2X - 87 = 0 Then: 2X = 87 X = 43.5
Assuming the question is "solve for x", the answer is x=5
2x+5y=20 Solve for y -2x -2x 5y=20-2x 5 5 5 y=4-2x 5
