Answer:
X= -9/10
y= -2 3/5
Step-by-step explanation:
Multiply equation one by 4 and equation two by 3 to eliminate X
it becomes
-12x + 8y =-12
12x - 3y = -1
add equation one and two,
you'll be left with 5y= -13
divide both sides by 5
y = -13/5 improper fraction
= -2 3/5
Now substitut y = -2 3/5 into any of the original equations to get x.
using equation two, we have
4x -(-2 3/5) = -1
4x + 2 3/5 = -1
4x = -1 - 2 3/5
the LCM of 5 is 5 , so
4x = -5-13/5
4x = -18/5
crossmultiply
4x x 5 = -18
20x = -18
divide both sides by 20
we have x = -18/20, when you cancel further , you have x = -9/10
