Calculate X:
−8x+5(3−x)=6−4x+3(x+1)
To solve this problem, we'll follow these steps:
- Step 1: Apply the distributive property to both sides.
- Step 2: Combine like terms on each side.
- Step 3: Move all terms involving x to one side and constants to the other.
- Step 4: Simplify to solve for x.
Now, let's work through each step:
Step 1: Distribute on the left: 5(3−x)=15−5x. So, the left side becomes −8x+15−5x.
Distribute on the right: 3(x+1)=3x+3. So, the right side becomes 6−4x+3x+3.
Step 2: Combine the like terms:
Left side: −8x−5x+15=−13x+15.
Right side: 6+3+3x−4x=9−x.
Step 3: Equating both sides, we have:
−13x+15=9−x.
Move all x-terms to one side and constant terms to the other:
Add 13x to both sides:
15=9+12x.
Step 4: Isolate x by subtracting 9 from both sides:
6=12x.
Divide both sides by 12:
x=126=21.
Therefore, the solution to the equation is x=21, which corresponds to choice 2.
