Answer:
4
Step-by-step explanation:
2x+19=x+23
We simplify the equation to the form, which is simple to understand
2x+19=x+23
We move all terms containing x to the left and all other terms to the right.
+2x-1x=+23-19
We simplify the left and right sides of the equation.
+1x=+4
We divide both sides of the equation by 1 to get x.
x=4
7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21
10x-40=50
Add 40 to both sides
10x=90
X=9
4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20
