Given that x:y=5:1 find 4x+5y:3x
kotykmax [81]

Answer:

5:3

Step-by-step explanation:

When the ratio says x:y=5:1, it means that x is 5 times greater than y. So, plug in 5 for x and 1 for y.

4(5)+5(1):3(5)

20+5:15

25:15 , if simplified then the ratio 5:3

2x + y = -4<br> 5x - 3y = 1<br><br> Solve with elimination method
Ivanshal [37]

Answer:

For the first equation the answer for "X" will be,

x =  \frac{ - 4 - y}{2}

if you want me to solve for y instead then the answer will be,

y =  - 4 - 2x

for the second equation the answer for "X" will be,

x =  \frac{1 + 3y}{5}

If you want me to solve for y instead then the answer will be,

y =  -  \frac{1 - 5x}{3}
