Use the numbers 0 through 9 to complete each equation so the statement about it's solution is true

One solution:
5-4+7x+1= (blank)x+ (blank)

Infinitely many solutions:
5-4+7x+1= (blank)x+ (blank)

Sorry if it's confusing. You basically fill in the blanks with numbers to match up with what the statement above it says about the solution of the equation.
