Answer:
ANSWER
On rewriting the given equations, we get
2x−3y+5=0 ...(i)
−4x+6y−10=0 ...(ii)
From (i) and (ii), comparing the coefficients gives

Answer:
X=2.5
Y=0
Step-by-step explanation:
SOLUTION:
This can be solved from elimination method
Step 1) multiply it any one term to make it same as second variable.
For instance multiply the first equation(4x+y=10)
by 3 and the seond equation by 1
4x+y=10 X3
2x+3y=5 X1
You will get,
12x+3y=30
- 2x+3y=5
By subtracting, you will get
10x=25
X=2.5......... (3)
By subtuting 3 in eq 1 (or 2)
4x+y=10
4(2.5)+y=10
10+y=10
Y=0
Therefore x=2.5 and y=0
