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
