Given the equation:

23x -17x - 42 = 2(21-6)

ANSWER: x=12

Step-by-step explanation:

Adding similar elements: 23x-17x=6x

6x-42=2(21-6)

Subtract the numbers: 21-6=15

6x-42=2*15

Multiply the numbers: 2*15=30

6x-42=30

Add 42 to both sides

6x - 42 + 42 = 30 + 42

Simplify

6x=72

Divide both sides by 6

(6x/6)=(72/6)

Simplify

x=12

ANSWER: x=12 There is a solution.
