Answer:
(- 3.5, - 5.5 )
Step-by-step explanation:
Given the 2 equations
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 and evaluate for y
Substituting into (1)
y = - 3.5 - 2 = - 5.5
Solution is (- 3.5, - 5.5 )

Hey there!
--------------------------
X² -25 = 0
We can use formula a² -b² =(a-b)(a+b)
x² - 5² =0
(x-5)(x+5)=0
x+5 =0 or x-5 = 0
x=-5 or x=5
Answer is x=-5, x=5
