Solve for X:
−8(4−x)+4(2x+5)=2(7−2x)
To solve this linear equation, we will proceed step by step:
- Step 1: Apply the distributive property to both sides of the given equation.
- Step 2: Combine like terms on both sides.
- Step 3: Rearrange the equation to isolate the variable x.
- Step 4: Solve for x and verify against the choices provided.
Now, let's work through each step:
Step 1: Apply the distributive property:
−8(4−x) becomes −32+8x and 4(2x+5) becomes 8x+20.
The right side 2(7−2x) becomes 14−4x.
This gives us the new equation:
−32+8x+8x+20=14−4x.
Step 2: Combine like terms:
On the left side: −32+20+8x+8x=−12+16x.
On the right side: 14−4x remains unchanged.
The equation simplifies to:
−12+16x=14−4x.
Step 3: Rearrange the equation to isolate x.
Add 4x to both sides to move the x terms to one side:
−12+16x+4x=14.
This simplifies to:
−12+20x=14.
Next, add 12 to both sides to isolate terms with x:
20x=14+12.
Thus, 20x=26.
Step 4: Solve for x:
Divide by 20:
x=2026=1013.
Therefore, the correct solution is x=1013, which corresponds to choice 3.
