2x + 10...the common number between these 2 terms is 2...so factor the 2 out
2(x + 5) <==
Here you have 2 linear equations and are to solve this system. Both equations have already been solved for y, so you can set one of them = to the other one:
-2x+11 = -3x+21.
Then 3x-2x = 21 - 11, or x = 10 (answer)
Find y by subst. x = 10 into either of the given equations.
Solution is then (10, ? )
The answer would be 75 width
The nearest whole number rounds to 6
The nearest tenth rounds to 5.70
The nearest hundredth rounds to 5.70
A - actuary...........that is the answer
