Answer:
x = 1 , y = - [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
3x - 4y = 6 → (1)
5x + 8y = - 1 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
6x - 8y = 12 → (3)
Add (2) and (3) term by term to eliminate y
11x = 11 ( divide both sides by 11 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
5(1) + 8y = - 1
5 + 8y = - 1 ( subtract 5 from both sides )
8y = - 6 ( divide both sides by 8 )
y = - [tex]\frac{6}{8}[/tex] = - [tex]\frac{3}{4}[/tex]
