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.
