Answer:
x = 3.7 ( nearest tenth )
Step-by-step explanation:
given the 2 equations
5x + 2y = 22 → (1)
- 2x + 6y = 3 → (2)
multiply the terms in (1) by - 3
- 15x - 6y = - 66 → (3)
Add (2) and (3) term by term, to eliminate the term in y
(- 2x - 15x) + (6y - 6y) = (3 - 66)
- 17x + 0 = - 63
- 17x = - 63 ( divide both sides by - 17 )
x = 3.7
