Solution of this equation
lara31 [8.8K]
2.5y + 3x = 27
5x - 2.5y = 5

Align the variables to make solving this easier.

2.5y + 3x = 27
-2.5y + 5x = 5

You can see that the 2.5y and -2.5y cancel each other out. Then add the 3x and 5x, and 27 + 5.

3x = 27
5x = 5

8x = 32

Divide both sides by 8.

x = 4

Now input that x into one of the equations to get y. 

2.5y + 3(4) = 27
2.5y + 12 = 27
2.5y = 15
y = 6

The answer to this system of equations is x = 4, y = 6. (4, 6)

PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Bond [772]

Answer:

R = \frac {3ST}{2S + T}

Step-by-step explanation:

Given the equation;

\frac {3}{R} - \frac {1}{S} = \frac {2}{T}

Rearranging the equation, we have;

\frac {3}{R} = \frac {2}{T} + \frac {1}{S}

Lowest common multiple (LCM) of S and T is ST.

\frac {3}{R} = \frac {2S + T}{ST}

Cross-multiplying, we have;

3ST = R(2S + T)

Making R, the subject of formula;

R = \frac {3ST}{2S + T}

Can someone help or show me how to simplify this equation 22.5+7(n-3.4)
Scorpion4ik [409]
<span>22.5+7 (n-3.4)=19.8n

We simplify the equation to the form, which is simple to understand
<span>22.5+7(n-3.4)=19.8n

Reorder the terms in parentheses
<span>22.5+(+7n-23.8)=19.8n

Remove unnecessary parentheses
<span>+22.5+7n-23.8=+19.8n

We move all terms containing n to the left and all other terms to the right.
<span>+7n-19.8n=-22.5+23.8

We simplify left and right side of the equation.
<span><span>-12.8n=+1.3

</span>We divide both sides of the equation by -12.8 to get n.
<span>n=-0.1015625</span></span></span></span></span></span></span>
