Sagot :

Answer:

a) 2x + y =12, x = 9-2y. Solution: x=5 and y=2

b) x + 3y=16, 2x - y = 11

Solution: x = 7 and y= 3

c) 2x+ y = 11, x - 2y = - 7. Solution: x = 3 and y=5

d) y=11-2x, 4x - 3y=-11

Solution: x=2 and y=7

Step-by-step explanation:

a) 2x + y = 12

b) x = 9-2y

Substitution:

a) 2(9-2y)+y = 12

18 - 4y + y = 12

18-12 = 4y -y

6 = 3y

6/3 = y

y = 2 and

X = 9 - 2(2) = 5
