Solve the following equation

Mathematics
1 answer:

Answer: \frac{- 1}{11}

Step-by-step explanation:

Note: the "." symbol stands for multiplication

Given,

\frac{2x+4}{3} \\  - \frac{5x-7}{2} = 5

First we the LCM = 6,

\frac{2(2x+4)}{2.3} - \frac{3(5x-7)}{3.2}= 5

Then, we join both sides, since they have same denominator

\frac{2(2x+4) - 3(5x-7)}{6} = 5

Multiply again

\frac{4x+8 - 15x+21}{6} = 5

Add the same numbers

\frac{-11x + 29}{6} = 5

Transpose 6 to the other side

-11x + 29 = 5.6

-11x + 29 = 30

Transpose 29 to the other side

-11x = 30 -29

-11x = 1

Transpose 11 to the other side to get answer

x = \frac{-1}{11}

Hope it helps! If you have any doubts, feel free to ask

X2 can be combined with X?
natulia [17]

Answer:

Your first instinct might be to go ahead and add the x terms together, BUT this would be a bad thing to do! You cannot combine the x2 and 2x, because the first term has an exponent (2) and the second one does not have an exponent; therefore, you cannot add them together!

HELP ASAP solve the equation using the properties of equality.<br><br><br>89= -5d+9
sergey [27]

Answer:

d = -16

Step-by-step explanation:

Step 1: Write equation

89 = -5d + 9

Step 2: Solve for <em>d</em>

<u>Subtract 9 on both sides:</u> 80 = -5d

<u>Divide both sides by -5:</u> -16 = d

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

89 = -5(-16) + 9

89 = 80 + 9

89 = 89

there are d horses in a field there are 16 more female horses than male horses of the horses in the field only 25% of the male h
Oduvanchick [21]
Use f and m for "female" and "male."  Then f = m + 16, and f + m = d (total)

So now we have the system of linear equations

f = m + 16
f + m = d

We can eliminate f by subst. m + 16 for f in the second equation:
                                                                                                           d-16
m + 16 + m = d, or 2m + 16 = d.  Find m.  2m = d - 16, so that m = --------
                                                                                                               2

Assuming that the male horses are either brown or black, and that 25% of these are brown, then the rest must be black.  This number is
