Question

Which of the following equations have the same solution? Solve all three equations separately, and explain each step.

Answer 1

I. 4x – 14 = 2x + 8
II. 3x – 21 = 12
III. the quantity of x minus 2, divided by 5 equals the quantity of 4x plus 2, divided by 25

Answer 2

@iGreen

Answer 3

Equation I = 11
Equation II = 11
Equation III = 12

Answer 4

Answer 6

Here's my work:

\(4x – 14 = 2x + 8\)
\(4x = 2x + 22\)
\(2x = 22\)
\(x = 11\)

\(3x – 21 = 12\)
\(3x = 33\)
\(3x = 11\)

\(\Large\frac{x-2}{5} = \frac{4x+2}{25}\)

Cross Multiply:

\(25x - 50 = 20x + 10\)
\(25x = 20x + 60\)
\(5x = 60\)
\(x = 12\)
