Question

solve the system by the substitution method
1/2x+1/5y=-11/10
1/2x+2y=5/2

Answer 1

is it difficult?

Answer 2

Am trying to compare what i got
if you can help!

Answer 3

Thanx

Answer 4

sure. i can.

Answer 5

I would proceed by multiplying the second equation by 2. Getting:
x+4y=5 Then express x in terms of y like: x=-4y+5. Substitute for x in the first equation: (1/2)(-4y+5) +1/5y = -11/10
-2y+5/2 +1/5y=-11/10
(-9/5)y=-11/10-5/2
(-9/5)y=-36/10
y=2

Answer 6

x+8=5
x=-3
(-3,2)

Answer 7

Thanx

Answer 8

How did this compare? with your answer

Answer 9
