Question

solve for x. 5.1 = 4x - 7.7 x =

Explanation:

Step1: Add 7.7 to both sides

To isolate the term with \( x \), we add 7.7 to both sides of the equation \( 5.1 = 4x - 7.7 \). This gives us \( 5.1 + 7.7 = 4x - 7.7 + 7.7 \). Simplifying the left side: \( 5.1 + 7.7 = 12.8 \), and the right side simplifies to \( 4x \) (since \( -7.7 + 7.7 = 0 \)). So now the equation is \( 12.8 = 4x \).

Step2: Divide both sides by 4

To solve for \( x \), we divide both sides of the equation \( 12.8 = 4x \) by 4. This gives \( \frac{12.8}{4} = \frac{4x}{4} \). Simplifying, we get \( x = 3.2 \).

Answer:

\( x = 3.2 \)
