Answer:
x=-4
y=1
Step-by-step explanation:
For the given system of equations,
2.5x-3y=-13.....eqn(1)
3.25x-y=-14.....eqn(2)
We first make y the subject of eqn (2)
This implies that,
y=3.25x+14.....eqn(3)
We substitute eqn (3) into eqn (1)
2.5x-3(3.25x+14)=-13
2.5x-9.75x-42=-13
-42+13=9.75x-2.5x
-29=7.25x
Dividing through by 7.25, we obtain
x=-4
We now put the value of x into eqn (2)
3.25(-4)-y=-14
This implies that,
-13+14=y
y=1
The answer to square root of 1.9321 is - 1.39
