Answer 1

x=

−1

14

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
