Question

How many solutions for x does the following equation have?

3(x + 8) − 1 = 3x + 4

A.
4
B.
1
C.
0
D.
infinite

Answer 1

c. 0

Explanation:

3(x+8) - 1 = 3x+4

3x+24-1 = 3x+4

3x+23 = 3x+4

There are no solutions since both equations have the same slope meaning they are parallel and they will never intersect since they have different y-intercepts.
