Question

solve the following by substitution method X by 3 + y by 4 equal to 4, 5 x by 6 - y by 8 equal to 4​

Answer 1

Answer:

y=-4;x=-16

Step-by-step explanation:

[x/3+y]×1/4=4......(1)&(5x/6-y)×1/8=4....(2)

(x/12+4y)=4

x=48+4y..{substitute this x value in (2)}

so we get..

5(48+4y)/8(6-y)=4

240+20y/48-8y=4

240-192=-32y-20y

-12y=48

y=-4
