Answer:
x = - 3.5 , y = - 5.5
Explanation:
y = x - 2 → (1)
y = 3x + 5 → (2)
substitute y = 3x + 5 into (1)
3x + 5 = x - 2 ( subtract x from both sides )
2x + 5 = - 2 ( subtract 5 from both sides )
2x = - 7 ( divide both sides by 2 )
x = - 3.5
substitute x = - 3.5 into either of the 2 equations for y
substituting into (1)
y = x - 2 = - 3.5 - 2 = - 5.5
then x = - 3.5 and y = - 5.5
