Answer:
C
Step-by-step explanation:
Answer:
x = 3 and x = 4
Step-by-step explanation:
3x - 4 + 4x - 8 = x^2
7x -12 = x^2
x^2 - 7x + 12 = 0
(-4)*(-3) = 12 and (-4)+(-3) = -7
(x-3)(x-4) = 0
x - 3 = 0. x = 3
x - 4 = 0. x = 4
The correct choice is the third one. Y=2/3x
Answer:
Step-by-step explanation:
Let the number be 'x'
x*8 + 6 = 7
8x + 6 = 7
8x = 7 - 6
8x = 1
x = 1/8
