Question

Are 2x + 5 = 9 and -2x = 4 equivalent to each other

Answer 1

Answer: no.

Step-by-step explanation: 2x + 5 = 9 so subtract 5 from each side you get 2x = 4

X= 2

If we substitute that back in 2(2) + 5 = 9 so

If you do -2(2) = 4 it’s -4=4 and it’s not equivalent to each other

Because the statement is not correct.

Answer 2

There are not equivalent to each other because the equation 2x+5=9 is equivalent to 2x=4
