step-by-step explanation:

your answer would be c

step 1: simplify both sides of the equation.

23x − 19x + 5 = 20

23x + − 19x + 5 = 20

(23x + − 19x) + (5) = 20 (combine like terms)

4x + 5 =20

4x+5=20

step 2:

step 2: subtract 5 from both sides.

4x + 5 − 5 = 20 − 5

4x = 15

step 3: divide both sides by 4.

answer: x =

in decimal form: 3.75
