Answer:
x = 2
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
lcm 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

Answer:
1) x = 2, y = 1
2) x = 2, y = 1
Step-by-step explanation:
3x + 2y = 8
take x as 2 and y as 1
3 x 2 + 2 x 1 = 6 + 2 = 8
2x + 3y = 7
take x as 2 and y as 1
2 x 2 + 3 x 1 = 4 + 3 = 7
