1 answer

Let's solve the equations one by one.

Question 1 Solve the equation for x:
\( 9x - 4 = 113 \)

Step 1: Add 4 to both sides of the equation:
\( 9x = 113 + 4 \)
\( 9x = 117 \)

Step 2: Divide both sides by 9:
\( x = \frac{117}{9} \)
\( x = 13 \)

So, the answer is:
A. x = 13


Question 2 Solve the equation:
\( 5(x + 11) = 55 + 5x \)

Step 1: Distribute 5 on the left side:
\( 5x + 55 = 55 + 5x \)

Step 2: Subtract \( 5x \) from both sides:
\( 55 = 55 \)

This statement is always true, which implies that the equation has infinitely many solutions.

So, the answer is:
C. All real numbers
