Solution for -3c-2=7 equation:

Simplifying

-3c + -2 = 7

Reorder the terms:

-2 + -3c = 7

Solving

-2 + -3c = 7

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + -3c = 7 + 2

Combine like terms: -2 + 2 = 0

0 + -3c = 7 + 2

-3c = 7 + 2

Combine like terms: 7 + 2 = 9

-3c = 9

Divide each side by '-3'.

c = -3

Simplifying

c = -3

What is the solution to -(6m+8)=4(17-m)

ale4655 [162]

Answer:

The solution to the problem is -38.

Step-by-step explanation:

-(6m + 8) = 4(17 - m)
=> -6m - 8 = 68 - 4m
=> -6m + 4m = 68 + 8
=> -2m = 76
=> m = 76/-2
=> m = -38

Hence, the solution to the problem is -38.
