Answer:
x=
−1
14
Step-by-step explanation:
Let's solve your equation step-by-step.
7−2(3x+4)=8x
Step 1: Simplify both sides of the equation.
7−2(3x+4)=8x
7+(−2)(3x)+(−2)(4)=8x(Distribute)
7+−6x+−8=8x
(−6x)+(7+−8)=8x(Combine Like Terms)
−6x+−1=8x
−6x−1=8x
Step 2: Subtract 8x from both sides.
−6x−1−8x=8x−8x
−14x−1=0
Step 3: Add 1 to both sides.
−14x−1+1=0+1
−14x=1
Step 4: Divide both sides by -14.
−14x
−14
