Please answer these all of these (If you can), and I know you can search it on go ogle so I need a detailed show of how you did it.

-22 + 8x = 28x - 42
-11x - 2 = 6 - 10x
4x + 8 = -13 + 7x
2x + 8 = x - 7
1. Answer is x = 1 Explanation: Rearrange terms -22 + 8c = 28x - 42 Add 22 to both sides of the equation 8x - 22 = 28x - 42 8x - 22 + 22 = 28x - 42 + 22 Simplify 8x = 28x - 20 Subtract 28x from both sides of the equation 8x = 28x - 20 8x - 28x = 28x - 20 - 28x Simplify -20x = -20 Divide both sides of the equation by the same term -20x/-20 = -20/-20
2. Answer is x = -8 Rearrange terms -11x - 2 = 6 - 10x -11x - 2 = -10x + 6 Add 2 to both sides of the equation -11x - 2 = -10x + 6 -11x - 2 + 2 = -10x + 6 + 2 Simplify -11x = -10x + 8 Add 10x to both sides of the equation -11x = -10x + 8 -11x + 10x = -10x + 8 + 10x Simplify -x = 8 Divide both sides of the equation -x = 8 -x/-1 = 8/-1 Simplify x = -8
3. Answer is x = 7 Rearrange terms 4x + 8 = -13 + 7x Subtract 8 from both sides of the equation 4x + 8 - 8 = 7x - 13 - 8 Simplify 4x = 7x - 21 Subtract 7x from both sides of the equation 4x = 7x - 21 4x - 7x = 7x - 21 - 7x Simplify -3x = -21 Divide from both sides -3x = -21 -3x/-3 = -21/-3 answer is x = 7
4. Answer is x = -15 Subtract 8 from both sides 2x + 8 = x - 7 2x + 8 - 8 = x - 7 -8 Simplify 2x = x - 15 Subtract x from both sides of the equation 2x = x - 15 2x - x = x- 15 - x Simplify x = -15
