Question

solve the equation by using
Coloss multiplication methool-
on +34-13 = 38-24-6=0​

Answer 1

Answer:

WER

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

4x−2y=4---(2)

Using formula for cross multiplication method:

(b

1

c

2

−b

2

c

)

x

=

(c

)

y

=

(a

)

−1

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

2×4−(−2)×10

x

=

10×4−3×4

y

=

3×(−2)−4×2
