Answer:
5) 3x - 10 = x + 4
answer: 7
6) 6x + 4 = x - 11
answer: -3
Step-by-step explanation:
3x - 10 = x + 4
x = 7
6x + 4 = x - 11
x = -3
Two
x² + 4 = 4x + 1
x² - 4x + 3 = 0
x² - 3x - x + 3 = 0
x(x - 3) - (x - 3) = 0
(x - 3)(x - 1) = 0
x = 1, 3
y = 4(1) + 1 = 5
y = 4(3) + 1 = 13
Two solutions: (1,5) (3,13)
