Okay post them 1 at a time
Evaluate the power,subtract the numbers then write all the numerator above the common denominator.
a = 2x - 18
remove the parenthesis and simplify
x - 3 + x - a = 15
2x - 3 - a = 18 ( add 3 to both sides
2x - a = 18 ( subtract 2x from both sides )
- a = 18 - 2x ( multiply through by - 1 )
a = - 18 + 2x
a = 2x - 18
Answer:
2 and 1/2
Step-by-step explanation:
:)
I'll give you the answers I'm good at these.
21 = 20
21 explained
twice a number is 60 more than so take 50+50=100
100-60=40
40\20=2
(but use 20)
20 X 5 = 100
