Answer:
x = -12, a = 17
Step-by-step explanation:
You can use algebraic techniques to simplify two-step equations. They have a constant on one side of the equation and a variable with a coefficient on the other. However, for algebraic equations, most will require you to add or subtract a constant from the side with the variable.
4x + 7 = -41 can be simplified algebraically. Subtract 7 from both sides and then divide by 4.
4x + 7 = -41
4x = -48
x = -12
-4 - 2a = -38 can also be simplified algebraically. Add 4 to both sides and then divide by -2.
-4 - 2a = -38
-2a = -34
a = 17
