When doing a problem like this, you need to know that you are going to multiply a fraction equal to 1. (x/x)

Ask yourself: what times 4 equals 12? 3. So we know our fraction equal to 1 is 3/3

What is 3 times 3? 9. So our complete fraction is 12/9

5x+2x=49

7x=49

x=7. 35 apples

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}
