Step-by-step explanation:
First we get the same denominator by finding a common multiple.
20 is the lowest common multiple so let's use that.
9/10 will have to change so that the denominator is 20.
From 10 to 20 we have multiplemultiplied it by 2 so we will do the same to the numerator.
9 × 2 = 18.
The fraction is now 18/20.
Now 3/4 – we will get to 20 by multiplying by 5.
3 × 5 = 15
Now we can compare
18/20 and 15/20
9/10 and 3/4
Y = x + 4
y = -x - 6
x + 4 = -x - 6
x + x = -6 - 4
2x = -10
x = -10/2
x = -5
y = x + 4
y = -5 + 4
y = -1
one solution : (-5,-1)
