Answer:

x=3

Step-by-step explanation:

1)  3(x+7)=6(x+2)

2)Multiply the number on the outside by the numbers on the inside

 3x+21 =6x+12

3)Subtract 3x from 6x. When you do that it cancels out itself on the side it came from leaving you with only 21 one that side.

21=3x+12

4)Subtract 12 from 21. When you do that it cancels out itself on the side it came from leaving you with only 3x on that side.

9=3x

5)  Divide 3x from both sides that will cancel out the x leaving you with only 1x and it will turn the 9 into 3.

9/3x=3x/3x

x=3

Lapatulllka [165]
<span>Brenda would be correct, another way to find the answer would be to use the keep change flip method. Where you keep 5/2 change division to multiplication then flip 4/1. The equation would then be 5/2 * 4/1 then you just multiply straight across 5*4 = 20 and 2*1 equals 2. You end up with 20/2 which reduces to 10</span>
