Help me please, if you don’t know, don’t answer. Thank you <3

Step-by-step explanation:

1). (B). Replace one equation with the sum/difference of both equation.

System B is

- 4x - 6y = 9 (1B)

-4x + 3x = - x

- 6y + y = - 5y

9 - 4 = 5

- x - 5y = 5 (2B)

2). Yes, both system are equivalent.

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

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  

x

2  

x

​    

=240

=48
