Answer:c

c = - 15

Explanation:

Simplifying

19c + 31 = 26c + -74

Reorder the terms:

31 + 19c = 26c + -74

Reorder the terms:

31 + 19c = -74 + 26c

Solving

31 + 19c = -74 + 26c

Solving for variable 'c'.

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

Add '-26c' to each side of the equation.

31 + 19c + -26c = -74 + 26c + -26c

Combine like terms: 19c + -26c = -7c

31 + -7c = -74 + 26c + -26c

Combine like terms: 26c + -26c = 0

31 + -7c = -74 + 0

31 + -7c = -74

Add '-31' to each side of the equation.

31 + -31 + -7c = -74 + -31

Combine like terms: 31 + -31 = 0

0 + -7c = -74 + -31

-7c = -74 + -31

Combine like terms: -74 + -31 = -105

-7c = -105

Divide each side by '-7'.

c = 15

Simplifying

c = - 15
