Answer:
x = 3
Step-by-step explanation:
Hello!
We can distribute the parenthesis and solve for x.
Solve
- 9 - 2(x - 5) = x + 10
- 9 - 2x + 10 = x + 10
- 19 - 10 = 3x
- 9 = 3x
- x = 3
The value of x is 3.
We can plug it back in to check if it works.
Check
- 9 - 2(x - 5) = x + 10
- 9 - 2(3 - 5) = 3 + 10
- 9 - 2(-2) = 3 + 10
- 9 + 4 = 3 + 10
- 13 = 13
Correct!
Answer:
[tex]\huge\boxed{\sf x = 3}[/tex]
Step-by-step explanation:
Given equation:
9 - 2(x - 5) = x + 10
Distribute
9 - 2x + 10 = x + 10
Subtract 10 to both sides
9 - 2x = x
Add 2x to both sides
9 = x + 2x
9 = 3x
Divide 3 to both sides
9/3 = 3x/3
3 = x
OR
x = 3
