Answer:
Steve is 5
Step-by-step explanation:
Steves sister is 25, she is 5 years more than 4 times steve is.
5 * 4 = 20 and the sister is 5 years older so,
Steve is 5
2x + 4 = x^2 + x - 2
x^2 + x - 2 - 4 - 2x = 0
x^2 - x - 6 = 0
(x - 3)(x + 2) = 0
x - 3 = 0 y = 2x + 4
x = 3 y = 2(3) + 4
y = 10
x + 2 = 0 y = 2x + 4
x = -2 y = 2(-2) + 4
y = 0
solutions are : (3,10) and (-2,0) <===
