Answer:
the answer is A
Step-by-step explanation:
It would be .5x-5= because it says 5 less so it would be subtract 5 from half of x.
<h2><u>
Answer:</u></h2>
x = 3
y = -8
<h2><u>
Step-by-step explanation:</u></h2>
x + y = -5
x - y = 11
Since the y's will cancel out, we don't need to modify the two equations in any way.
Now, just add the two equations.
x + x = 2x
y + (-y) = 0
-5 + 11 = 6
2x = 6
Divide by 2.
x = 3
To find y, plug 3 in as "x" in one of the two equations.
3 + y = -5
y = -8
Answer:
4 hours
Step-by-step explanation:
3+1=4
Add 5 to both sides to get x alone and you will have your answer which is x= -3
