By setting the coefficients of x in both sides equal to each other:
4x = ?x
This equation has infinite solutions when the coefficients are equal and non-zero. Therefore, any value of x can be substituted in for the question marks to create an equation with infinite solutions. For example:
4x + 10 = 4x + 10
Solve the problem so that there are infinite solutions
4x+10= ?x + ?
