Solve the following system of equations.<br> 5x+2y =-6<br> 3x-2y = 22
katen-ka-za [31]

Answer:

5x+2y =-6 ........1

3x-2y = 22 ........2

Add both Equations

we get

8x = 16

Divide both sides by 8

x = 2

Substitute x = 2 into any of the equations

3(2) - 2y = 22

-2y = 22 - 6

- 2y = 18

Divide both sides by -2

y = - 9

x = 2 y = - 9

Hope this helps

△ABC △ABC  is similar to △LMN △LMN . Also,  side AB measures 5 cm,  side AC measures 7 cm, and  side L​M measures 35 cm.
dolphi86 [110]
You need to apply "Proportionality theorem" here:
LM / AB = LN / AC
35 / 5 = LN / 7
LN = 7 * 7
LN = 49

In short, Your Answer would be 49 cm

Hope this helps!
