Answer:

x=\frac{275}{62} , y=\frac{127}{31}

Step-by-step explanation:

<h3>I will use the elimination method.</h3>

We want to make the X's the same:

24x-15y=45

24x+16y=172

Because the signs of the X's are the same we subtract the 2 equations to make:

(I put the second one on top of the 1st)

31y=127

So:

y=\frac{127}{31}

Substitute y into either equation 1 or 2:

(I chose equation 1)

8x-5(\frac{127}{31})=15

8x=5(\frac{127}{31}) + 15

x=\frac{5(\frac{127}{31})}{8}

So:

x=\frac{275}{62}

Step by step workout of ;<br> log x^3+log 5x=5 log 2-log 2/5
Charra [1.4K]

Answer:

x = 2

Step-by-step explanation:

log  \: {x}^{3}  + log \: 5x = 5log \: 2 - log \:  \frac{2}{5}  \\  \\  \therefore \: log( {x}^{3}  \times 5x) = log  {2}^{5} - log \:  \frac{2}{5}  \\  \\ \therefore \: log( 5{x}^{4}) = log 32 - log \:  \frac{2}{5} \\  \\ \therefore \: log( 5{x}^{4}) = log  \bigg(32  \times  \frac{5}{2}  \bigg) \\  \\ \therefore \: log( 5{x}^{4}) = log  \bigg(16  \times  5) \\  \\ \therefore \: 5{x}^{4}=  16  \times  5 \\  \\ \therefore \: {x}^{4}=   {2}^{4}   \\  \\  \huge \purple{ \boxed{\therefore \: {x} = 2}}
