2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
7x + 4 = 2x + 5Subtract 4 from each side of the equation:7x = 2x + 1Subtract 2x from each side:5x = 1Divide each side by 5:x = 1/5 = 0.2
2x-6=4 6+4=2x 10=2x 10/2=x 5=x x=5
2x+4 = -16 2x = -16-4 2x = -20 x = -10
2x + 4 is an expression, not an equation. There can be no solution set for an expression.
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
2x = 8 Divide both sides by 2: x = 4 So, the solution set is {4}
If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
-2x + 4 < 10 -4 -4 --------------------- -2x < 10 --- ---- (divide) -2x -2x ---------------- -x > -5 (switch the sign when you divide by a negative) Hope that helps :)
Since the problem should read like this -4 < 9x - 10 - 7x The process of getting the solution set of x|x ? would be 1. first perform all like number actions, by subtracting 9x - 7x = 2x , which makes the problem -4 < 2x - 10 2. now we have to get all like terms to the same side, in this case we need to get the -10 to the left side, the problem reads. -4 + -10 < 2 - 10 + 10 The problem then becomes, -14 < 2x to get x alone, divide both sides by 2 -14 / 2 < 2x / 2 the solution set therefore becomes x|x < 7
2x + 4 = 14 (subtract 4 from both sides) 2x = 10 (divide both sides by 2) x = 5
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
4 - 2x = 10 -2x = 10-4 -2x = 6 -x = 3 x = -3
2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
-6x2 + 17x -12. To get the solution, we set up the formula as follows: (2x - 3) * (4 - 3x) Then we multiply each of the components as follows: (2x * 4) + (2x * -3x) + (-3 * 4) + (-3 * -3x) Then we simplify as follows: 8x + -6x2 + -12 + 9x -6x2 + 17x + -12 -6x2 + 17x -12
do you mean: 2x-4=6 1. add 4 to both sides 2x=10 2. divide by 2 on both sides so you can get "x" by itself. x=5 3. answer
