Question

Which of the following pairs of equations have the same solutions?

• A. 6x = 3 and 3x = 1.5
• B. 8x = 3 and 4x = 1
• C. 10x = 9 and 5x = 18
• D. 12x = 6 and 6x = 6

Answer 1

The correct option is A 6x = 3 and 3x = 1.5

The pair of equations 6x = 3 and 3x = 1.5 have the some solutions.
$6x=3\Rightarrow x=\frac{3}{6}$
$\Rightarrow x=\frac{1}{2}\Rightarrow x=0.5$
and $3x=1.5\Rightarrow x=\frac{1.5}{3}\Rightarrow x=0.5$
