Question

Find the simplest form of the equation $30x+10=40$.

• A. $3x+1=4$.
• B. $x=1$.
• C. $x=3$.
• D. $\frac{1}{3}\times x=3$.

Answer 1

The correct option is C $x=3$.

Consider equation $30x+10=40$.
Divide the equation by 10, we get, $3x+1=4$.
Subtract 1 from both sides, we get, $3x=3$.
Divide 3 on both sides, we get, $x=3$.
