Respuesta :
1/2(18-5x)=1/3(6-4x)
1/2x(18-5x)=1/3x(6-4x)
18-5x=2/3x(6-4x)
18-5x=4-8/3x
54-15x=12-8x
-15x+8x=12-54
-7x=-42
x=6
1/2(18−5x)=1/3(6−4x)
Step 1: Simplify both sides of the equation.
1/2(18−5x)=1/3(6−4x)
9+−52x=2+−43x
−52x+9=−43x+2
Step 2: Add 4/3x to both sides.
−52x+9+43x=−43x+2+43x
−76x+9=2
Step 3: Subtract 9 from both sides.
−76x+9−9=2−9
−76x=−7
Step 4: Multiply both sides by 6/(-7).
(6−7)*(−76x)=(6−7)*(−7)
x=6
Answer:
x=6
