x=9
Step-by-step explanation:
4x+6+7x+15=120 combine like terms it becomes 11x+21 =120 take away 21 from 120 , leaves you with 11x=99 divide by 11 to get x alone leaves you with x=9 :)
Answer:
ab = 42
Step-by-step explanation:
4x + 6 + 7x + 15 = 120
combine like terms
11x + 21 = 120
subract 21 from both sides
11 x = 99
x = 9
plug in to double check 9 in 4x + 6 + 7x + 15
meaning 4 times 9 + 6 + 7 times 9 + 15
36 + 6 + 7 times 9 + 15
Then simplify,
42 + 7 times 9 + 15
Then simplify again,
42 + 63 + 15
Then simplify one last time,
42 + 78
and your answer is
120
meaning the X is right so now plug in the X in 4x +6
and your answer is 42
