Question

Which linear equation has only one solution?

A. 3(2x+1)=6x-2
B. 2(x+3)=2x+6
C. 4x-1=2x+4
D. 3x-2=3x+5

Answer 1

Answer: C is the equation with one solution. 2x = 5 x = 2 1/2

Explanation:

choices A and D have no solutions. A.) 6x + 3 ≠ 6x - 2 D.) 3x - 2 ≠ 3x + 5

B has infinite solutions 2x + 6 = 2x + 6 is true for any value of x.
