Question

solve this with substitution method :- 2x+3y=1 and 3x+2y=7​

Answer 1

Step-by-step explanation:

3x +2y = 8 eq 1, 2x +3y = 7 eq 2

3x = 8- 2y

x = 8-2y/3

sub x = 8-2y/3 in eq 2

2[8-2y/3] + 3y = 7

16-4y/3 + 3y = 7

Icm of 3, 1 = 3 16-4y +9y/3 = 7

16-4y+9y = 21

16 +5y = 21

5y = 21-16

5y = 5

y = 5/5

y = 1

x = 8-2y/3

x = 8-2*1/3

= 8-2/3

= 6/3

x = 2
