Y = 3

Exp:

10 + 12y = 2y + 40
- 2y = - 2y

10 + 10y = 40
-10 -10

10y = 30

Part 10, What is the area of this figure? NO LINKS!!!​
Tamiku [17]

Answer:

shaded area  = 601 mm²

Step-by-step explanation:

Area of rectangle = Length * Breadth

Area of first section = 12 * 16 = 192 mm²

Area of 2nd middle section = 8 * ( 16 - 10 ) =  48 mm²

Area of the bottom section = 19 * 19 = 361 mm²

Area of total therefore = 192 mm² + 48 mm² + 361 mm²

                                      =  601 mm²

Solve using the elimination method:<br> X-3y=7<br> 3x + 3y=9
sergij07 [2.7K]

Answer:

                        x=4\\\\y=-1

Step-by-step explanation:

Given Equation:

x-3y=7      Equation:1

3x + 3y=9     Equation:2

Dividing Equation:2 by '3' both the sides:

x+y=3      

or   x=3-y     Equation:3

Putting the vale of 'x' in Equation:1

                             x-3y=7

                          (3-y)-3y=7\\\\3-y-3y=7\\\\3-4y=7\\\\

Subtracting '3' both sides

                             -4y=7-3\\\\-4y=4

                                 y=\frac{4}{-4}

                                 y=-1

Putting value of 'y' in Equation:3

                                x=3-y

                                x=3-(-1)\\\\x=3+1\\\\x=4

The solution of the equations is :

                              x=4\\\\y=-1
