Answer:

-8/3

Explanation:

Step one: Simplify parentheses:

-18x + 12 = 60

Step two: divide everything by 6

-3x + 2 = 10

Step three: isolate the variable

-3x = 10-2

-3x = 8

x = -8/3

Hello!

Answer:


\large \boxed{\sf x =-(8)/(3) }

Explanation:

→ We want to solve this equation:


\sf -3(6x-4)=60

Simplify the left side:


\sf \sf (-3) * 6x- (-3) *4=60


\sf \sf -18x+12=60

Subtract 12 from both sides:


\sf \sf -18x+12-12=60-12

Simplify both sides:


\sf \sf -18x=48

Divide both sides by -18:


\sf \sf (-18x)/(-18) = (48)/(-18)

Simplify both sides:


\sf x = (48)/(-18)

Simplify the fraction:


\sf x = (6 * 8 )/(6 * (-3))


\boxed{\sf x =-(8)/(3) }

Conclusion:

The solution of the equation -3(6x-4)=60 is -8/3.
