2(x + 7) + 3x = 12
what is the first step in solving this equation for x?
a) 2x + 14 + 3x = 12
b) 2x + 7 + 3x = 12
c) 2x + 14 = 9
eliminate
d) 5x = -2

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

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
