Vaselesa [24]3 years ago

The solution is x = -61/8 and y = -1/2.

<u>Step-by-step explanation</u>:

The given equations are -4x + 3y = 29 and 2y + 5 = 4

   <u>Step 1</u> : There is no x term in the second equation.

   <u>Step 2</u> : Solve for y, 2y = 4 -5

                                      y = -1/2

   <u>Step 3</u> : Substitute y = -1/2 in first equation and solve for x.

   <u>Step 4</u> : -4x + 3(-1/2) = 29

                 -4x -(3/2) = 29

                 -8x -3 = 29\times2

                 -8x = 58 + 3

                  x = -61/8

What is the value of x in the diagram below?
VARVARA [1.3K]

Answer:

<h2>7.2</h2>

option B is the right option.

Step-by-step explanation:

<h3>Using leg rule</h3>

\frac{bc}{ab}  =  \frac{ab}{bd}

Plug the values:

\frac{20}{12}  =  \frac{12}{x}

Apply cross product property

20 \times x = 12 \times 12

Calculate the product

20x = 144

divide both sides of the equation by 20

\frac{20x}{20}  =  \frac{144}{20}

Calculate:

x = 7.2

hope this helps..

Good luck...
