5x+4y-4=0
x-20=12y

Remember do this with SUBSTITUTION METHOD.
I Will mark you as brainliest if you answer correctly

Answer 1

Hence, y=-3/2 and x=2

PLZZ mark me as BRAINLIEST

THANK YOU

Answer 2

Answer:

Step-by-step explanation: 5x+4y-4=0.......... 1)

X-20=12y.......... 2)

From equation 2

X=12y+20

Put x=12y+20 in equation 1

5(12y+20) +4y-4=0

60y+100+4y-4=0

96+64y=0

64y= -96

y= -94/64 = -3/2

Put y=-3/2 in x= 12y+20

x=12y+20

12×-3/2+20

-18+20=2

I HOPE IT HELPS YOU........
