2(3x+7)+x=70
mutiply the bracket by 2
(2)(3x)(2)(7)+x= 70
6x+14+x= 70
6x+x+14= 70 ( combine like terms)
7x+14= 70
move 14 to the other side
sign changes from +14 to -14
7x+14-14=70-14
7x= 56
divide both sides by 7
7x/7= 56/7
x=8
Answer: x= 8
-16x+144=128
answer is 128x-80
Answer:
-16.3 ≥ q
Step-by-step explanation:
–5.3 ≥ 6.7 + 4.3 + q
Combine like terms
–5.3 ≥ 11 + q
Subtract 11 from each side
–5.3-11 ≥ 11-11 + q
-16.3 ≥ q
Answer:
66.666%
Step-by-step explanation:
6/9=x/100
9x=6x100
9x=600
x=600:9
x=66.666
66.666/100=66.666%
