Question

x + y = 6
5x − y = 3

Answer 1

Answer:

x + y=6

5x - y=3

by using elimination method -y and +y cancel each other

then x+5x=6x & 6+3=9

There fore 6x=9

x=9÷6

x=3÷2 or 1.5

Answer 2

Answer:

x = 7/5 ; y = 4

Step-by-step explanation:

to eliminate x we need to multiply first equation by -5

-5x-5y=-30

5x-y=3

add both equations

-6y=-27

y=-27/-6

y=9/2

y=4

sub y value in any equation

5x-4=3

5x=7

x=7/5
