Question

Solve each of these equations. Explain your reasoning.

1.2(3x+2)=2x+28


2.5y+13=-43-3y


3.4(2a+2)8(2-3a)

Answer 1

2(3x+2)=2x+28

6x + 4 = 2x + 28

4x = 24

x = 6

OK. I did the first one. Now you can do the other two. We'll be glad to check your answer.

Answer 2

1. distribute the 2 into the brackets to obtain
6x + 4 = 2x + 28
Then take your letters(variables) to one side and your numbers to the other.
2. Just add 3y to both sides to balance the equation
5y+3y+13 = 43 - 3y +3y
8y+13 = 43
Now subtract 13 from both sides to balance the equation and continue...
3. I believe you have left out the equal sign. Distribute the 4 into the left hand side brackets and the 8 into the right hand side brackets. Then get your letters(variables) to one side and your numbers to the other...
