Answer:
Explanation:
45x+6y=15
-x+18y = 11
let's use elimination, the other way is by substitution, either way works but, it looks to me like elimination would be easy with the 'y'
3(45x+6y=15)
135x + 18y = 45 ( subtract 2nd eq. from 1st )
-( -x+18y = 11 )
136x +0y =34
x = 34 /136
x = 1 /4
there is X
plug that back into either of the 1st or 2nd equations to solve for y
- 1/4 + 18 y = 11
18y = 11 1/4
18y = 45/4
y = 45/4 * 1/18
y = 45/ 72
the fractions seem "difficult" but that's just what the given problem finds
