For the equation -3x - 20 to have an infinite solution, it should be equal to -3x + 20 = -3x + 20, so the blank will be + 20
Given the data in the question,
Let the equation be - 3x + 20 = - 3x blank
These situations could be turned into producing an infinite number of solutions only if the lines are coincident and have the same y-intercept.
The quantities being coincident demonstrates the equality of the expressions printed on the left and right sides.
The lines with the same slopes are equal lines.
If the lines are making equal patterns, they will be giving infinite answers as output. As we can see in the result the equations are containing infinite solutions.
So, the missing blank will be = +20 to make the equation have infinite solutions.
Therefore, the value of the blank will be +20 and the equation will be =
- 3x + 20 = - 3x + 20
