Answer 1

Answer:

Answer: x=2. y=1. Step-by-step explanation: by substitution method. 2x+3y=7-----(1). 5x-2y=8-----(2). from eq. (1). x=7-3y/2------(3).

Answer 2

Answer:

x=20/11

y= -6/11

Step-by-step explanation:

5x+2y=8----(i)

2x+3y=2----(ii)

Multiply (i) by 2 & (ii) by 5

=>10x+4y=16----(iii)

and, 10x+15y=10---(iv)

Subtracting (iii) from (iv)

10x+15y-10x-4y=10-16

11y=-6

y=-6/11

Putting y=-6/11 in (i)

5x+2(-6/11)=8

=>x=20/11
