Question

2x+y=7
y-3=0
Do this question by substitution method​

Answer 1

2x+y=7 ...... (i)

y-3=0 .......(ii)

From (ii)

y-3=0

y=3 ...... (iii)

Substitute (iii) into (i) :

2x + 3 = 7

2x = 4

x = 2

SO the answers are :

x = 2 , y = 3

Answer 2

Step-by-step explanation:

2x+y=7 ...... eq (1)

y-3=0 ......eq (2)

taking eq (2)

y-3=0

y=3

substitution of y=3 in eq (1)

2x+y=7

2x+3=7

2x=7-3

2x=4

x=4/2

x=2

° x=2 and y= 3
