Answer:
(
, 3)
Step-by-step explanation:
Given the 2 equations
2x + 5y = 16 → (1)
10x - 3y = - 4 → (2)
Multiplying (1) by - 5 and adding to (2) will eliminate the term in x
- 10x - 25y = - 80 → (3)
Add (2) and (3) term by term
(10x - 10x) + (- 3y - 25y) = (- 4- 80) ← simplify
- 28y = - 84 ( divide both sides by - 28 )
y = 3
Substitute y = 3 into (1) or (2) for corresponding value of x
(1) : 2x + 15 = 16 ( subtract 15 from both sides )
2x = 1 ( divide both sides by 2 )
x = ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
