Which of the following equations have the correct solution? Select all that apply 3n+7=16;n=3

11=2/3x-1;x=15

x+3/-6 =2x;x=3/13
the x+3/-6 is all one fraction

20-2t=1/2+28;t=-3.2

4+y-2-2y=16+y; no solutions

60=1/4 g+12;g=12

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
