Question

enter a number into each box to create an equation that has an infinite number of solutions.
$7(4x + 6) - x = \square x + \square$

Explanation:

Step1: Expand left-hand side

First, expand $7(4x + 6)$:
$7(4x + 6) = 28x + 42$

Step2: Combine like terms

Combine the $x$-terms on the left:
$28x + 42 - x = (28x - x) + 42 = 27x + 42$

Step3: Match for infinite solutions

For an equation $Ax + B = Cx + D$ to have infinite solutions, $A=C$ and $B=D$. So the right-hand side must equal $27x + 42$.

Answer:

27, 42
