Question

2x-5y=4. 3x+5y=18 by elimination method​

Answer 1

Answer:

2x-5y=4 be equation (i)

3x+5y=18 be equation (ii)

add equation (i) +equation (ii)

5x=22

x=22/5

y=24/25

Answer 2

Answer:

x = 22/5 = 4.4

y = 24/25 = 0.96

Step-by-step explanation:

2x - 5y = 4 ------ (i)

3x + 5y = 18 ------ (ii)

Using Elimination method ,

Add (i) and (ii),

2x - 5y + 3x + 5y = 4 + 18

5x = 22

$x=\frac{22}{5} \\\\x=4.4$

2x - 5y = 4

2(4.4) - 5y = 4

8.8 - 5y  = 4

5y = 8.8 - 4

5y = 4.8

$y=\frac{4.8}{5} \\\\y=\frac{48}{50} \\\\y=\frac{24}{25} \\\\y = 0.96$
