Question

solve,

4x-y+20=0

6x+5y-9=0 ... find x and y by equating coefficients method

Answer 1

Answer:

x=-91/26

y=-123 23/26

keep it

Answer 2

Step-by-step explanation:

4x-y+20=0 - - - (1)

6x+5y-9=0 - - - (2)

(1)×5 = 20x-5y+100=0 - - (3)

(3)+(2)

= 26x+91=0

X=-91/26

4(-91/26)-y+20=0

-182/13+2600/13-y=0

2418/13-y=0

y=2418/13
