How many solution does following equtitions have 7x+21=21

Mathematics
1 answer:
Kaylis [27]3 years ago
8 0

One solution.

7x + 21 = 21 \\ 7x = 21 - 21 \\ 7x = 0 \\ x = 0

If we can solve for the value of x. Then the solution would be one only for system of linear equations.

For your information, When the equation is true or rather say that both sides are the same, the solution will be infinite.

When the equation is false or rather say that both sides have different number or value then there won't be any solutions.

Which value of x is in the solution set of the following inequality. -3x +5 >7
Vadim26 [7]
I’m not sure if this was a typo, but A and B are the same answer. A and B are correct, because when you solve this the answer has to be anything less than -0.6.
