Solve these simultaneous equations by elimination: a. 2x y = 6 4x + 3y = 22

Question:

Solve these simultaneous equations by elimination:

a. 2x − y = 6

4x + 3y = 22

b. 7x + 3y = 16

2x + 9y = 29

c. 5x + 2y = 6

3x − 10y = 26

d. 2x − y = 12

6x + 2y = 21

e. 3x − 2y = −6

6x + 3y = 2

f. 3x + 8y = 33

6x = 3 + 5y
