Question

Solve the following pair of linear equations using cross multiplication method:2x - 5y = 14x+2y=-2please give me the Ans as soon as possible ​

Answer 1

Answer:

x=b1c2-b2c1÷a1b2-a2b1

x=(-5)×2-2×(-14)÷2×2-1×(-5)

x=-10+28÷4+5

x=18÷9=2

for y=a1c2-a2c1÷a1b2-a2b1

y=2×2-1×(-14)÷2×2-1×(-5)

y=4+14÷4+5

y=18÷9

y=2

so the required point is (2,2)
