Question

Irene says the equation 9x+15=3x+15 has no solution because 9x is greater then 3x. is he right yes or no and explain why

Answer 1

X=0

Explanation:

If we subtract 15 from both sides, then we can see 9x=3x. If x was 0, then the equation would be 9x0=3x0. Since 0 times anything equals 0, this equation would be true resulting in 0=0.

Answer 2

This equation has one solution, if x = 0

Explanation:

Because, you subtract 15 from both sides so: 9x + 15 - 15 = 3x + 15 - 15 which equals: 9x = 3x. if x = 0 this equation is true.
