2x - 5(x - 4) = - 9 + 4x + 8

X=3

Explanation:2x-5(x-4)=-9+4x=8

2x-5x+20=-9+4x+8

2x-5x-4x=-9-20+8

-7x/-7=-21/-7

x=3

X=3

Explanation:

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

2x−5(x−4)=−9+4x+8

Step 1: Simplify both sides of the equation.

2x−5(x−4)=−9+4x+8

2x+(−5)(x)+(−5)(−4)=−9+4x+8(Distribute)

2x+−5x+20=−9+4x+8

(2x+−5x)+(20)=(4x)+(−9+8)(Combine Like Terms)

−3x+20=4x+−1

−3x+20=4x−1

Step 2: Subtract 4x from both sides.

−3x+20−4x=4x−1−4x

−7x+20=−1

Step 3: Subtract 20 from both sides.

−7x+20−20=−1−20

−7x=−21

Step 4: Divide both sides by -7.

−7x

−7
