Question

enter a number into each box to create an equation that has an infinite number of solutions.
$3(2x + 5) - x = \square x + \square$

Explanation:

Step1: Expand the left-hand side

$3(2x + 5) = 6x + 15$

Step2: Subtract $x$ from the result

$6x + 15 - x = 5x + 15$

Step3: Match for infinite solutions

For the equation $5x + 15 = \square x + \square$ to have infinite solutions, the coefficients and constants must be equal, so the boxes are 5 and 15.

Answer:

$5x + 15$
