Question

X=y+2
x+4y=7by substitution method

Answer 1

x =y +2..........1

put value of x in eq 2

x + 4y = 7

(y+2) + 4y = 7

5y +2 = 7

5y = 7 -2

5y = 5

y = 1

x = y +2

x = 1 +2

x = 3

Answer 2

Step-by-step explanation:

x-y=2 .........1

x+4y=7 ............2

From equation 1

x=y + 2 ......3

putting value of equation 3 in equation 2

y+2+4y =7

5y=5

y=1

Now,

Substituting value of y in equation 3

x=y+2

x=1+2

x=3

Therefore x=3 and y = 1
