Answer:
x = 1.5 , y = 0.5
Step-by-step explanation:
y = - x + 2 → (1)
y = 3x - 4 → (2)
substitute y = 3x - 4 into (1)
3x - 4 = - x + 2 ( add x to both sides )
4x - 4 = 2 ( add 4 to both sides )
4x = 6 ( divide both sides by 4 )
x = = 1.5
substitute x = 1.5 into either of the 2 equations and solve for y
substituting into (1)
y = - 1.5 + 2 = 0.5
