What is the solution to the system of equations? Use the substitution method. {y=−2x+5 {3x−4y=2 Enter your answer in the boxes.
Nataly_w [17]
1. You have the following equations:
<span>
 y=−2x+5  (i)
 3x−4y=2  (ii)

 2. You must substitute the equation (i) into the equation (ii), as below:

 </span>3x−4y=2
 3x-4(−2x+5)=2
 3x+8x-20=2
 11x-20=2

 3. Now, you must clear the variable "x":

 11x=2+20
 x=22/11
 x=2

 4. You have the value of "x", so you can find the value of "y". When you substitute x=2 into the equation (i), you obtain:

 y=−2x+5
 y=-2(2)+5
 y=-4+5
 y=1

 5. Therefore, the answer is:

 x=2
 y=1

Answer:

 A. 74 cm

Step-by-step explanation:

First, we break the rhombus down into similar shapes,

The area of 2 triangles = The area of a square

So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,

10 multiplied by 5 =50

Thats the area of rectangle 1

Rectangle 2

3 multiplied by 6 = 18

Triangle

4 times 3 divided by 2 = 6

Thus

6 + 18 + 50  = 74
