Solve for X in the Linear Equation: 7 - x = 15 - 5

Question

Solve for X:

7−x=15−5 7 - x = 15 - 5

Step-by-Step Solution

First, simplify the right side of the equation:
15−5=10 15 - 5 = 10
Hence, the equation becomes 7−x=10 7 - x = 10 .
Subtract 7 from both sides to isolate x x :
7−x−7=10−7 7 - x - 7 = 10 - 7
This simplifies to:
−x=3 -x=3
Divide by -1 to solve forx x :
x=−3 x=-3
Therefore, the solution is x=−3 x=-3 .

Answer
