Solve the system: 4x – 3y = -21 X=-y-14

Liula [17]

Answer:

The solution for the system of equations is

x=2,y=−2

Explanation:

4x−3y=14.....equation (1)

y=−3x+4.....equation (2)

Solving by substitution

Substituting equation 2 in equation 1

4x−3⋅(−3x+4)=14

4x+9x−12=14

13x=14+12

13x=26

x=2

Finding y by substituting x in equation 1

4x−3y=14

4⋅2−3y=14

8−3y=14

8−14=3y

3y=−6

y=−2

victus00 [196]

Answer:

The area of larger triangle is 48 ft².

Step-by-step explanation:

Assuming that the area of triangle formula is A = 1/2 × base × height. Then, you have to substitute the following values :

$area = \frac{1}{2} \times b \times h$

$let \: b = 12,h = 8$

$area = \frac{1}{2} \times 12 \times 8$

$area = \frac{1}{2} \times 96$

$area = 48 \: {feet}^{2}$

What value of x makes the following equation true? 15+3x=3(2−2x)

Alinara [238K]

Answer:

$\boxed {x = -1}$

Step-by-step explanation:

Solve for the value of $x$ :

$15 + 3x = 3(2 - 2x)$

-Use Distributive Property:

$15 + 3x = 3(2 - 2x)$

$15 + 3x = 6 - 6x$

-Take $6x$ and add it to $3x$ :

$15 + 3x + 6x = 6 + 6x - 6x$

$15 + 9x = 6$

-Subtract both sides by $15$ :

$15 - 15 + 9x = 6 - 15$

$9x = -9$

-Divide both sides by $9$ :

$\frac{9x}{9} = \frac{-9}{9}$

$\boxed {x = -1}$

Therefore, the value of $x$ is $-1$ .
