Question

Use any method applicable to solve the simultaneous equations below

a)X-y=0
X+y=8

b)2x+3y=2
3x+2y=-2

Solve by elimination method
5x+4y=9
5x+2y=7

Answer 1

Step-by-step explanation:

x-y=0

X+y=8

on equating those two

2x= 8

X=8/2=4

as

x-y=0

4-y=0

-y=0-4

-y= -4

y=4

those two above are also same
