Question

enter a number into each box to create an equation that has an infinite number of solutions.
$7(6x + 3) - x = \square x + \square$

Explanation:

Step1: Expand the left-hand side

$7(6x + 3) = 42x + 21$

Step2: Subtract $x$ from the result

$42x + 21 - x = 41x + 21$

Step3: Match for infinite solutions

For the equation $41x + 21 = \square x + \square$ to have infinite solutions, the coefficients of $x$ and constants must be equal on both sides. So the first box is 41, the second is 21.

Answer:

$41x + 21$
