Solve for the unknown number in the following expressions. a. \( y \div 3=4 R 2 \) b. \( 33 \div x=4 \) R 5 a. \( y=\square \)

To solve the expression \( y \div 3 = 4 R 2 \), we start by noting that the remainder (R) tells us how much is left over after the division. Since 4 multiplied by 3 is 12, adding the remainder of 2 gives us \( y = 12 + 2 = 14 \). For the second expression \( 33 \div x = 4 R 5 \), we first convert it to an equation. We know \( 4 \times x + 5 = 33 \). Solving for \( x \): \( 4x = 33 - 5 \) gives \( 4x = 28 \), so \( x = 7 \). So, a. \( y = 14 \) b. \( x = 7 \)
