Answer:
x=12
Step-by-step explanation:
10x-11+3x-2+3x+1=180
We simplify the equation to the form, which is simple to understand
10x-11+3x-2+3x+1=180
We move all terms containing x to the left and all other terms to the right.
+10x+3x+3x=+180+11+2-1
We simplify left and right side of the equation.
+16x=+192
We divide both sides of the equation by 16 to get x.
x=12
