The first step would be :
E) 3x + (2x + 4) = -7
Answer:
Add 7 to both sides
Step-by-step explanation:
You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.
Then you would get 4x = -8.
Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.
x = -2
Try and get the variable by its self by -81 from both sides then divide it by 7 and get ur answer.
