Answer 2

Resposta:

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

5−(4x+12)=8+2(x−1)

Step 1: Simplify both sides of the equation.

5−(4x+12)=8+2(x−1)

5+−1(4x+12)=8+2(x−1)(Distribute the Negative Sign)

5+−1(4x)+(−1)(12)=8+2(x−1)

5+−4x+−12=8+2(x−1)

5+−4x+−12=8+(2)(x)+(2)(−1)(Distribute)

5+−4x+−12=8+2x+−2

(−4x)+(5+−12)=(2x)+(8+−2)(Combine Like Terms)

−4x+−7=2x+6

−4x−7=2x+6

Step 2: Subtract 2x from both sides.

−4x−7−2x=2x+6−2x

−6x−7=6

Step 3: Add 7 to both sides.

−6x−7+7=6+7

−6x=13

Step 4: Divide both sides by -6.

−6x/−6=13/−6

Answer:

x=−13/6 (Decimal: -2.166667)
