Well 7x+2x=9x and 9x - 1 = 9x - 1
so the answer should be 9x-1
Answer:
(1.5, 3)
Step-by-step explanation:
Given the 2 equations
2x + 3y = 12 → (1)
y = x + 1.5 → (2)
Substitute y = x + 1. 5 into (1)
2x + 3(x + 1.5) = 12 ← distribute and simplify left side
2x + 3x + 4.5 = 12
5x + 4.5 = 12 ( subtract 4.5 from both sides )
5x = 7.5 ( divide both sides by 5 )
x = 1.5
Substitute x = 1.5 into (2) for corresponding value of y
y = 1.5 + 1.5 = 3
Solution is (1.5, 3)
Sure !
At 5 PM, it was 7.1° .
Then the sun went down, a cold front moved in,
and the temperature started dropping.
It dropped from 7.1° down to zero, and it didn't stop there.
It kept on dropping some more.
After it went down to zero, it dropped another 10.3° .
All together, it dropped 7.1° plus 10.3° .

Answer: 2x+21</h3>
=============================
Work Shown:
f(x) - g(x) = [ f(x) ] - [ g(x) ]
f(x) - g(x) = [ 7x+15 ] - [ 5x-6 ]
f(x) - g(x) = 7x+15 - 5x+6
f(x) - g(x) = (7x-5x)+(15+6)
f(x) - g(x) = 2x+21
You type "they both ... " This indicates that there are TWO people involved, not just one.
"<span>plus 20% per month plus 15% commission" isn't quite clear. Is that 20% of the base pay ($1,250)? I assume that the 15% commission is figured on the sales ($20,000)
Please clarify this as much as you can.</span>
