Question

What is 4(x+3) = 2(2x+9) What is x

Answer 1

First distribute 4 into the corresponding parenthesis.
4x+12
Then distribute 2 into the other corresponding parentheses.
4x+18
So together you get 4x+12=4x+18
No we want to get all our variables on one side and our numbers on the other side.
We can do this by combining like terms/
First subtract 12 from both sides
4x=4x+30
Then subtract 4x from both sides
0=30
The equation is false
