43 + 114 + x = 180
Solve for x.
Ms. Sue, I am not an expert but I know that the numbers all have to be on one side and the letter on the other
Ex.
43+114+X=180
114+43=157
157+X=180
Do the opposite operation to get letter alone so it would be -157 on both sides..
157+X=180
-157+X=180-157
X=23
Hope that helps
