Solve the system of equations. -4x+7y = 20 & y=3x+15
andreyandreev [35.5K]

Substitute y = 3x + 15 to the equation -4x + 7y = 20:

-4x + 7(3x + 15) = 20          <em>use distributive property</em>

-4x + (7)(3x) + (7)(15) = 20

-4x + 21x + 105 = 20     <em>subtract 105 from both sides</em>

17x = -85     <em>divide both sides by 17</em>

x = -5

Substitute the value of x to the equation y = 3x + 15:

y = 3(-5) + 15

y = -15 + 15

y = 0

<h3>Answer: x = -5 and y = 0</h3>

Isabella spent $49 for 7 bracelets. Each bracelet cost the same amount.
n200080 [17]
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.

Equation: number of bracelets bought × cost of each bracelet = total cost

Number of bracelets bought: 7
Total Cost: 49

Using this information, we can fill in the equation and solve for x.

7x = 49

To isolate x, divide both sides by 7.

x = 7

Since x equals 7, we now know that each bracelet cost $7.

If the area of a rectangle with length (4x) is 4x^2+12x. Find the width.
almond37 [142]
Area=lenght times widht
area/length=width
(4x²+12x)/(4x)=width
we can factor out the 4x
4x²+12x=4x(x+3)


so the width is x+3
