Answer:
m - n - 4
Step-by-step explanation:
9m + 4n - 1 - 6m - (n + 3) - (2m + 4n)
= m - n - 4
Substitution!
<span>y = 4x – 10...(1)
y = 2...(2)
You have y=2 here, substitute it in equation (1),
</span><span>y = 4x – 10
</span><span>2 = 4x – 10
</span>Add both sides by 10
12=4x
Divide both sides by 4
x=3
We have x=3, and y=2. ==> (x,y) = (3,2)
