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
