Q9. Solve for cin the following equation. 5c+7=42 c=7 c=6 c=49/5 c=44

To solve for \( c \) in the equation \( 5c + 7 = 42 \), follow these steps:<br /><br />1. Subtract 7 from both sides of the equation to isolate the term with \( c \):<br /><br /> \[<br /> 5c + 7 - 7 = 42 - 7<br /> \]<br /><br /> \[<br /> 5c = 35<br /> \]<br /><br />2. Divide both sides by 5 to solve for \( c \):<br /><br /> \[<br /> c = \frac{35}{5}<br /> \]<br /><br /> \[<br /> c = 7<br /> \]<br /><br />Therefore, the correct answer is \( c = 7 \).
