If (9−3x)−(17x−10)=−1, then the value of x is:
- A1
- B−1
- C9/10
- D-9/10
Solution & Step-by-step Explanation
Given the linear equation:
(9−3x)−(17x−10)=−1
Expand and remove the parentheses:
9−3x−17x+10=−1
Combine like terms:
(9+10)+(−3x−17x)=−1
19−20x=−1
Rearrange the terms to isolate x:
19+1=20x
20=20x
x=
20
20
=1
