Answer:
1) Equation: 2x+6 = -2x-2
Solution: x = -2
2) Equation: 2 = -8-1x
Solution: x = -10
3) Equation: 3x-2 = 4
Solution: 2
Explanation:
1) Add the "x" and "1" boxes on each side to form 2x+6 = -2x-2.
2x+6 = -2x-2
Add 2 to the -2 on the right and to the 6 on the left, making it:
2x+8 = -2x
Subtract 2x from the 2x on the left and -2x on the right, making it:
8 = -4x
Divide -4 on both sides, making the answer:
x = -2
2) Add the 1's, x's, and -x's on both sides, making it:
2 = -8-1x
Then add 8 on both sides, making it:
10 = -1x
Divide -1 on both sides, making the answer=
x = -10
3) Individually add the boxes on each side, making it:
3x-2 = 4
Add 2 on both sides, making it:
3x = 6
Divide 3 on both sides, making the answer=
x = 2
