Answer:
5x - y = 10x + 3y = 4
5x - y = 4..... 1
10x + 3y = 4.....2
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)
I dont know im trying to figure that out
Answer:
-8
Step-by-step explanation:
when you solve for x you get -8 but when you pkug it back in both sides are not equal, making it extranious
I’m not a true percent sure but I think it’s C
The second one is the answer
