This problem, we're being asked to determine if the given equation is an identity, a conditional equation, or if it's a contradiction.
00:07
Well, the only way to determine that is to go ahead and solve.
00:11
Well, i notice we have decimals here, all of which are in the 10's place.
00:14
So in order to get rid of the decimals, i'm going to multiply both sides of our equation by 10.
00:19
Because remember, multiplying by 10 will just move the decimal point one place to the right.
00:24
So when we multiply 10 by this first quantity, really, we just multiply it by 0 .3.
00:28
Well, 10 times 0 .3 is 3.
00:31
So we have 3 times x plus 2.
00:34
And the same thing happens when we multiply 10 by our second quantity.
00:37
We really just multiply it by the number in the front, and 10 times negative 0 .5 is negative 5.
00:43
Again, times x plus 2...
