A would be the very first step in solving the equation for x
You have to distribute 2 to x and 7.
2(x + 7) + 3x = 12
2x + 14 +3x = 12
Answer:
A) 2x + 14 + 3x = 12
Step-by-step explanation:
The first step is to distribute the 2
2(x + 7) + 3x = 12
2x+14 +3x =12
Then we combine like terms
5x+14 =12
Subtract 14 from each side
5x+14-14=12-14
5x = -2
Then divide each side by 5
5x/4 = -2/5
x = -2/5
