Math question help please?
can the expression 2x and x + 2 ever have the same value? if so, what must the value of x be?
Yes, x would be 2
2x means "x" multiplied by 2, and x + 2 means simply "x" added 2, so the only way the value can be the same is if x=2 and the value is 4
Yes, 2(2) = 4 and 2+2 = 4, so x = 2.
Yes. The two expressions have equivalent values. 2x,(2?2) equals four. 2+2 equals four as well. The both have the same value.
