Answer: x= 47 (If that says 3x+2)(the picture is a little blurry)
Step-by-step explanation:
Linear pairs of angles sum to 180.
37+(3x+2) =180
Combine like terms
39+ 3x = 180
Subtract 39 from both sides
3x = 141
Divide both sides by 3
x= 47
3x8+4 because 3 times so that is 3 x the sum of 8 and 4 so 8+4 together it would be 3x8+4
Hi there! The answer is 0 solutions.

First we need to work out the parenthesis (for instance possible by using rainbow technique).

Now subtract 12.

Now we can see that the right side of the equation is always 8 smaller than the left side of the equation. Because the right is always smaller, this equation cannot be solved. Therefore there are no solutions to this equation. The answer is 0 solutions.
