Solve the following system of equations using the elimination method 5x - y = 10 x + 3y = 4​

5x - y = 10x + 3y = 4

5x - y = 4 1

10x + 3y = 42

multiply by -2 in eq 1 in both sides

-10x + 2y = -8

10x +3y = 4

eliminate one variable by adding the equations

5y = -4

y = - 4/5

sub the value of y in..1

5x - y = 4

5x + 4/5 = 4

5x = 16/5

divide by 5 on both sides

x = 16/25

(x ; y)

(16/25 ; -4/5)

2425
