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.

For the first equation, to get an equation that only has 1 solution your two missing numbers could be 3x and 6. This is because when you solve it, you get 7x + 2 = 3x + 6
- 3x
4x + 2 = 6
- 2
4x = 4
x = 1

For the second equation, your two numbers could be 7x and 4, because it means that x has to be different as 7 multiplied by one number and added to 2 cannot equal 7 multiplied by the same number but added to 4.

I hope this helps!
