Question

solve this equation through substitution​

Answer 1

Step-by-step explanation:

first equation will be

X+2y=1.6

second equation will be

7=10(X+y/2)

7=10x+10y/2

7×2=10x+10y

14=10x+10y

10x+10y=14

this is second equation

substitute now first equation

therefore,X=1.6-2y

put this value in second equation

therefore,10(1.6-2y)+10y=14

16-20y+10y=14

16-10y=14

-10y=14-16

-10y=-2

y=1/5

similarly find x
