Answer:
(2,1)
Step-by-step explanation:
Let's solve your system by elimination.
6x−7y = 5;−4x+7y=−1
6x−7y=5
−4x+7y=−1
Add these equations to eliminate y:
2x = 4
Then solve2x = 4for x:
2x = 4
(Divide both sides by 2)
x = 2
Now let's plug x in to solve for y.
6x - 7y = 5
6(2) - 7y = 5
12 - 7y = 5
subtract 12 on both sides.
-7y = -7
divide both sides by -1
y = 1

Answer:
19.125
Step-by-step explanation:
multiply 15.5 by 3 and then divide the answer by 4
Minus m-n = 36 so 36 is your answer.
6x = 90
x = 90/6
x = 15
4x + 10y = 90
4(15) + 10y = 90
60 + 10y = 90
10y = 30
y = 3
Answer: Last option
x = 15, y = 3
