question 49 of 50
solve for u.
u + 3.5 = 7.43
question 50 of 50
solve for x.
x - 2.7 = 5.26

Explanation:

Question 48

Step1: Divide both sides by 2

To solve for \( x \) in \( 5.12 = 2x \), we divide both sides of the equation by 2.
\( x=\frac{5.12}{2} \)

Step2: Calculate the division

\( \frac{5.12}{2}=2.56 \)

Step1: Subtract 3.5 from both sides

To solve for \( u \) in \( u + 3.5=7.43 \), we subtract 3.5 from both sides of the equation.
\( u=7.43 - 3.5 \)

Step2: Calculate the subtraction

\( 7.43-3.5 = 3.93 \)

Step1: Add 2.7 to both sides

To solve for \( x \) in \( x - 2.7=5.26 \), we add 2.7 to both sides of the equation.
\( x=5.26 + 2.7 \)

Step2: Calculate the addition

\( 5.26+2.7 = 7.96 \)

Answer:

\( 2.56 \)
