What is the solution to the following system of equations 2x+3y=3 and -3x-2y=8
SpyIntel [72]
<span>2x+3y=3
</span><span>-3x-2y=8

3y=3-2x
-2y = 8+3x

y = 1 - 2x/3
y = -4 - 3x/2

</span>1 - 2x/3 =  -4 - 3x/2

5 = - 3x/2 + 2x/3

5 = -9x/6 + 4x/6

5 = -5x/6

x = 5 * 6/-5

x = -6

No plug it in.

<span>2x+3y=3 ; x = -6

-12 + 3y = 3

3y=3+12

3y=15

y = 5

So </span>x = -6 and y = 5

PLEASE HELP!!<br><br> Solve the equation. Please show your math work step by step. 5x −14=−34
MrMuchimi

Hey

The Answer is -4x


Heres the Step by Step work


You add 14 to each side because it is negative, so

5x-14=-34

    +14|+14

and you will end up with

5x=-20

Divide 5 on each side, so

5x=-20

/5x | /5x


-20 / 5x =

x=-4

 or

-4x

27. If three more than one-fourth of a number is
ololo11 [35]

Answer:

8

Step-by-step explanation:

let the number be n , then

\frac{1}{4} n + 3 = n - 3 ( multiply through by 4 to clear the fraction )

n + 12 = 4n - 12 ( subtract 4n from both sides )

- 3n + 12 = - 12 ( subtract 12 from both sides )

- 3n = - 24 ( divide both sides by - 3 )

n = 8

That is the number is 8
