Answer:
-46
Explanation:
2x+43=2x-3
We simplify the equation to the form, which is simple to understand
2x+43=2x-3
We move all terms containing x to the left and all other terms to the right.
+2x-2x=-3-43
We simplify left and right side of the equation.
0x=-46
0=-46
The left and right sides are not equal, therefore there is no solution. This equation is invalid.
