To solve the equation \( 12 x=3+2 x+19 \), we first simplify the right side: 1. Combine like terms on the right: \( 3 + 19 = 22 \), so the equation becomes: \( 12 x = 2 x + 22 \). 2. Next, we isolate \( x \) by subtracting \( 2 x \) from both sides: \( 12 x - 2 x = 22 \), which simplifies to: \( 10 x = 22 \). Now that we know \( 10 x = 22 \), let's compare this with the options given: - A. \( 10 x + 16 \): This actually becomes \( 22 + 16 = 38\) when \( 10 x = 22 \). - B. \( 14 x + 10 \): If we substitute \( x \) from \( x = \frac{22}{10} = 2.2 \), it doesn't match. - C. \( 2(7 x + 5) \): Substituting \( x = 2.2 \) gives \( 2(7(2.2) + 5) = 2(15.4 + 5) = 2(20.4) = 40.8\), which isn't equivalent. - D. \( 14 x + 16 \): Similarly, this doesn't prove equivalent since it leads to a different sum. - E. \( 17 x + 13 \): Testing this would yield no matching terms. After checking all options, none of them are equivalent as \( 10 x = 22 \).
