sqrt of 2x + 15 = x
I think according to my calculations it would be 5, correct?
sqrt root of 7-x = 3-solve for x
My choice would be 2
Is that correct-
I squared both sides and came out with 7-x = 9
and then x = 2
Thank you for taking the time to check this
5 is correct for
sqrt(2x + 15) = x
Notice that parentheses are required to show an expression correctly.
For the second one, would you like to double check:
7-x = 9,
7 - 2 = 9?
Should it be (-2) instead of positive 2
