3(x – 4) + 7 = 5x? Help please.

-5/2

Step-by-step explanation:

Let's solve your equation step-by-step.

3(x−4)+7=5x

Step 1: Simplify both sides of the equation.

3(x−4)+7=5x

(3)(x)+(3)(−4)+7=5x(Distribute)

3x+−12+7=5x

(3x)+(−12+7)=5x(Combine Like Terms)

3x+−5=5x

3x−5=5x

Step 2: Subtract 5x from both sides.

3x−5−5x=5x−5x

−2x−5=0

Step 3: Add 5 to both sides.

−2x−5+5=0+5

−2x=5

Step 4: Divide both sides by -2.

-2x/2 = -5/2

x= -5/2
