Please help quickly!!:)) Appreciate it x+y=6 y+4=x Choices: (11/2, 1/2) (5, 1) (21/2, 11/2) (1, 5)

B: (5,1)

Step-by-step explanation:

So we have the system of equations:

We can solve this system using substitution.

Substitute the second equation into the first. Use x. So:

Combine like terms:

Subtract 4 from both sides:

Divide both sides by 2:

So, the value of y is 1.

To find x, substitute this back into the second equation:

Substitute 1 for y:

Add:

Therefore, our answer is (5,1).

The answer is B.

And we're done!

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
