Question

please i need this answer​

Answer 1

Answer:

x=2, y=1

Step-by-step explanation:

Given, equations

x+y=3

3x-2y=4

Now,

∆ = det(1,1 3,-2) = 1×-2 - 1×3 = -2-3 = -5

∆x = det(3,4 1,-2) = 3×-2 - 1×4 = -6-4 = -10

∆y = det(1,4 3,3 ) = 1×4 - 3×3 = 4-9 = -5

Now,

x = ∆x/∆ = -10/-5 = 2

y = ∆y/∆ = -5/-5 = 1
