Answer:
x = 6.
Explanation:
Let's solve your equation step-by-step.
3x − (7−x) = 1/2 (5x+4)
Step 1: Simplify both sides of the equation.
3x−(7−x)= 1/2 (5x+4) 3x+−1(7−x)= 1/2 (5x+4)(Distribute the Negative Sign)
3x+(−1)(7)+−1(−x)= 1/2 (5x+4) 3x+−7+x 1/2 (5x+4)
3x+−7+x=( 1/2 )(5x)+( 1/2 )(4)(Distribute)
Step 2: Subtract 5/2x from both sides.
4x−7−52x=52x+2−52x32 x−7=2
Step 3: Add 7 to both sides.
32x−7+7=2+732x=9
Step 4: Multiply both sides by 2/3.
(23)*(32x)=(23)*(9)
x=6
