Answer:
These steps can be used:
- combine -6 and 4
- combine 15 and -3
- multiply 2 by x and -2
Step-by-step explanation:
The equation could be solved as follows:
2(x -6 +4) = 15 -3 given
2(x -2) = 15 -3 combine -6 and 4
2(x -2) = 12 combine 15 and -3
2x -4 = 12 multiply 2 by x and -2
2x = 16 add 4 to both sides
x = 8 divide both sides by 2
_____
Alternate solution
At step 4, you could have
x -2 = 6 divide both sides by 2
x = 8 add 2 to both sides
