Translating this sentence into symbols:  2(x+3) = x - 5

So 2x + 6 = x - 5                    and x = -11

Check:  Is 2(-11+3) = -11 -5?               Is -16 = -16?  YES.  x =-11 is right.

Lisa had 1750 stamps. Mark had 480 fewer stamps than Lisa. Lisa gave some stamps to Mark. Now Mark has three times as many stamp
FrozenT [24]
L: 1750, M:1750-480=1270
Lisa gave some stamps to Mark so Lisa now has 1750-x and Mark has 1270+x. Mark also has 3 times as many as Lisa now: (1750-x)*3=1270+x
5250-3*x=1270+x
4*x=3980, x=3980/4, x=995
So Lisa gave 995 stamps to Mark.
At first Mark had 1270 stamps. Lisa now has 1750-995=755 stamps.

\log_a x = y \\ is same as a^y = x where a>0 and a is not equal to 1.

\log_3 x = 11 \\\\x = 3^{11}

Thus, exponential form is x = 3^{11}
