Answer:
see explanation
Step-by-step explanation:
given the 2 equations
4x + y = 2 → (1)
- 2x + y = 5 → (2)
Eliminate the term in y by subtracting (2) from (1) term by term
(4x - (- 2x) + (y - y) = (2-5)
6x = - 3 ( divide both sides by 6 )
x = [tex]\frac{-3}{6}[/tex] = - [tex]\frac{1}{2}[/tex]
substitute this value into either (1) or (2) and solve for y
(1) : - 2 + y = 2 ( add 2 to both sides )
y = 4
solution is ( - [tex]\frac{1}{2}[/tex], 4)
