Question

Can someone help me and explain how to solve this system of equation? Will medal and fan!

x+y=5

.10x+.25y=20

Answer 1

you can solve this by substitution
from the first equation:-
x = 5 - y

Answer 2

so replace the x in the second equation by 5 - y
and solve this equation for y

Answer 3

Elimination would be easier.

Answer 4

How would elimination be easir?

Answer 5

*easier?

Answer 6

Answer 7

Nvm. :\

Answer 8

Okay, @welshfella

thescond equation with the combination method would be

.10(5-y)+.25y=20

Answer 9

yes

Answer 10

Okay so

.5-.5y+25y=20

.5-30y=20

Answer 11

I mean. 25.5y

Answer 12

isn't it 0.25y?
5 - .10y + .25y = 20
.15y = 15

Answer 13

Okay, so y=100?

Answer 14

No - i made a mistake in my last post
its 0.5 not 5
so we have
0.15y = 20 - 0.5 = 19.5

Answer 15

130?

Answer 16

yes

Answer 17

no plug in 130 to x + y = 5 to get value of x

Answer 18

*now

Answer 19

x+130=5?

Answer 20

yes

Answer 21

Okay, I think I have it from here, thanks!
