Answer:

25/3 which also equals to 8.3333333

Explanation:

Step 1: Simplify both sides of the equation.

−8(x−5)=−3x−7+x−3

(−8)(x)+(−8)(−5)=−3x+−7+x+−3(Distribute)

−8x+40=−3x+−7+x+−3

−8x+40=(−3x+x)+(−7+−3)(Combine Like Terms)

−8x+40=−2x+−10

−8x+40=−2x−10

Step 2: Add 2x to both sides.

−8x+40+2x=−2x−10+2x

−6x+40=−10

Step 3: Subtract 40 from both sides.

−6x+40−40=−10−40

−6x=−50

Step 4: Divide both sides by -6.

−6x−6

=

−50−6

x=

25/3
