One positive number is three more than twice another. If their product is 629, find the numbers.
sineoko [7]

Answer:

x = 17 and y = 37

Step-by-step explanation:

Let the numbers be x and y.

y = 3 + 2x

xy = 629

substituting y in the second equation we get

x(3+2x) = 629

3x + 2x^{2} = 629

2x^{2} + 3x - 629 = 0

Solving a quadratic equation by using its formula:

x = [-3 ±√(9-4(2)(-629)] / 4

x = [-3 ± √5041] / 4

x = [-3 ± 71] / 4

x = 17 and \frac{-37}{2}

Ignore the negative number in x and just use x = 17 in the first equation we get

y = 3 + 2(17) = 37

10. What is the value of x in the solution to the system of equations?
RUDIKE [14]

Solve for x in first equation:

x-2y=7

Add “2y” to both sides

x=2y+7

Put this in to second equation:

3(2y+7)+2y=21

Solve for y:

Distribute the 3 into the ()

6y+21+2y=21

Combine the like y terms

8y+21=21

Subtract 21 from both sides

8y=0

Divide by 8 on both sides

y=0

Put this into the first solved equation:

x=2(0)+7

Solve for x:

Multiple 2(0)

x=0+7

Add 0 and 7

x=7

So the value of x is positive 7.

I need help with this Two-step equation<br><br> 18-4x= -2<br><br> Can anyone help?
Ksenya-84 [330]
<span>- - Star to simplify both sides of the equation.

</span>18-4x=-2&#10;

<span>- - Now you have top subtract 18 from both sides.
</span>
-4x+18-18=-2-18
- - Solve: 
-4x=-20&#10;

<span>- - And divide both sides by -4.

- - Solve: 
</span>\frac{-4x}{-4} =  \frac{-20}{-4}

x=5
