22=7x+1 (take 1 of each side of the equals)
21=7x (divide each side by seven)
3=x (BAM! answer)
It has one double solution.
It's the equation of a straight-line graph. Every point on the line is a solution of the equation. There are an infinite number of them.
-5
Without an indication of the equals sign, this is not an equation.
Not sure what you mean; that equation certainly has a solution.
It has one double solution.
It's the equation of a straight line. Every point on the line is a solution to the equation. There are an infinite number of them.
There is no solution since the equation is inconsistent.
It's the equation of a straight-line graph. Every point on the line is a solution of the equation. There are an infinite number of them.
x = 0 and y = 4
The equation does not have a solution.
There are an infinite number of ordered pairs that satisfy the equation.

There is no solution. There is no number that can be put in place of 'x' that can make that statement true.
What is the number of integral solution to x plus y plus z equals 100?
