Question

Solve the equation.
x - 2/7 = 3
A. x=-3 2/7
B. x=-2 5/7
C. x= 2 5/7
D. x= 3 2/7

Answer 1

You want to isolate x and solve for it. To do so, you need to get rid of the constants first and in this case it would be -2/7. Since this is a subtraction, \(x \large \color{red}{-}\frac{2}{7}\) you would need to add \(\frac{2}{7}\) to both sides of the equal sign to make sure that there is a balance. Not only that but you will also cancel -2/7 out and have x alone (-2/7 + 2/7 = 0).

Answer 2

\[x - \frac{2}{7} = 3 \rightarrow \color{green}{x - \frac{2}{7} + \frac{2}{7} = 3 + \frac{2}{7} \rightarrow x = ? }\]

Answer 3
