Question

What is 7x + 15 = 9x + 15 - 2x + 1 and how many solutions are there

Answer 1

Step-by-step explanation:

7x + 15 = 9x + 15 - 2x + 1

7x + 15 = 7x + 16

Bringing like terms on one side

7x - 7x = 16 - 15

x = 1

7x + 15 = 9x + 15 - 2x + 1

7x + 15 = 7x + 16

Bringing like terms on one side

15 - 16 = 7x - 7x

-1 = x

There are two solutions

Answer 2

Answer:

no solutions

Step-by-step explanation:

7x + 15 = 9x + 15 - 2x + 1

Combine like terms

7x+15 = 7x+16

Subtract 7x from each side

7x+15-7x = 7x+16-7x

15 =16

This is not a true statement so there are no solutions
