How do you simplify (23x - 15y) + (4x + 45y)

subract x from a side il do 23x - 4x so the equation would be (19x - 15y) + 45y then subtract y from a side so ill do 45 y -15y which would be 30 y making the equation 19x + 30y

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
