Answer 2

To solve the equations, we need to isolate the variable (a and x) on one side of the equal sign. Let's solve each equation step by step:

1. Equation: a - 43 = 7

To isolate 'a', we need to get rid of the constant term (-43) on the left side of the equation by performing the inverse operation.

Add 43 to both sides of the equation:

a - 43 + 43 = 7 + 43

Simplify:

a = 50

So the solution for 'a' is a = 50.

2. Equation: x + 15 = 65

To isolate 'x', we need to get rid of the constant term (15) on the left side of the equation by performing the inverse operation.

Subtract 15 from both sides of the equation:

x + 15 - 15 = 65 - 15

Simplify:

x = 50

So the solution for 'x' is x = 50.

Therefore, the solutions to the given equations are:

a = 50 x = 50
