VARIABLES ON BOTH SIDES A 16x-7=11x-32 B -4x-10=2x+20 a. Equation A A Equation B c. Both A and B d. Neither A nor B

To determine which equations have variables on both sides, we need to analyze each equation individually.<br /><br />Equation A: $16x-7=11x-32$<br />In this equation, we can see that there is a variable $x$ on both sides of the equation. Therefore, equation A has variables on both sides.<br /><br />Equation B: $-4x-10=2x+20$<br />In this equation, we can also see that there is a variable $x$ on both sides of the equation. Therefore, equation B also has variables on both sides.<br /><br />Based on our analysis, the correct answer is:<br />c. Both A and B
