Using
cross multiplication​

Answer 1

Answer:

3x+2y=10---(1)

4x−2y=4---(2)

Using formula for cross multiplication method:

(b1c2−b2c1)x=(c1a2−a1c2)y=(a1b2−a2b1)−1

So, from equation (1) and (2) we can write the value of a,b and c.

2×4−(−2)×10x=10×4−3×4y=3×(−2)−4×2−1

8+20x=40−12y=−6−8−1

28x=28y=
