For this case we have the following expression:
We apply distributive property, which by definition establishes that:
So:
Answer:
Since you are given two equations
y = 2x - 5
y = x^2 - 5
Substitute into one of the equations...,
;x^2 - 5 = 2x - 5
;x^2 - 2x = -5 + 5
; x^2 - 2x = 0
Hence you factorise the equation..,
; x(x - 2) = 0
Hence....x = 0 and 2
And for the value of y
; Substitute with the value of x onto one of either equations
for...x = 2
;y = 2(2) - 5....y = -1
for...x = 0
;y = 2(0) - 5....y = -5
