Answer:
The answer is D :)
Step-by-step explanation:
You take the smaller one (SQR) and subtract it from the big value (PQR) which gives you 126. Then you take 15 from it and get 111 which you have to divide by 2 and it gives you 55.5
Answer:
x = 2, y = -1
Step-by-step explanation:
To find x, use elimination.
multiply everything in x - y = 3 by 2
(x - y = 3)2
that will now become 2x - 2y = 6
now line the equations up.
4x + 2y = 6
2x - 2y = 6
Now add everything going down.
4x + 2x is 6x, 2y and -2y cancel out, and 6 + 6 is 12. the equation is now:
6x = 12
divide on each side.
x = 2
to find y, substitute 2 into x - y = 3
2 - y = 3
-y = 1
y = -1
