Answer:

Step 1: Simplify both sides of the equation.

6(3x−5)−7x=25

(6)(3x)+(6)(−5)+−7x=25(Distribute)

18x+−30+−7x=25

(18x+−7x)+(−30)=25(Combine Like Terms)

11x+−30=25

11x−30=25

Step 2: Add 30 to both sides.

11x−30+30=25+30

11x=55

Step 3: Divide both sides by 11.

x=5

Answer: x=-3

Step-by-step explanation:

6(3x - 5) - 7x = 25

18x-30-7x=25

-25x-30=25

-25x-30+30=25+30

-25x=75

-25x/-25=75/-25

x=-3
