-2x + 6 + 22 = -2x + 28
If: y = x+6 and y = 2x Then: x+6 = 2x And: 6 = 2x-x => 6 = x So: x = 6 and y = 12
5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.
-3x + 2x = 6Let's abbreviate left part by cancellation:-x = 6The answer will be:x = -6
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
Isolating xx = (6+6)/32x = 0.375
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
X = 6
The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
(2x+4)/3 = 6Multiply both sides of the equation by 3:(2x+4)/3*3 = 6*32x+4=182x+4-4 = 18 -4 Subtract 4 from both sides2x = 142x/2 = 14/2 Divide both sides by 2 to solve for xx = 7
2x-6 < 5+7x 2x-7x < 5+6 -5x < 11 x > -2.5
Solution: 2x + 6 = 2 2x = -4 x = -2 Check: LHS = 2*(-2) + 6 = -4 + 6 = 2 = RHS
-2x + 6 + 22 = -2x + 28
Without an equality sign it can't be considered to be an equation.
