Answer:

Answer:

8 1/4

Step-by-step explanation:

6 3/5 ÷ 0.8

6 3/5 = 33/5

0.8 = 8/10

6 3/5 ÷ 0.8

= 33/5 ÷ 8/10

= 33/5 * 10/8 ( Because multiplication and division are inverse operations)

= 33/4

= 8 1/4

2x-3y=8 -5x+2y=13 find The x coordinate

Answers

2x - 3y = 8
-5x + 2y = 13
Multiply the first equation by 2 and the second by 3.
2(2x - 3y = 8)
3(-5x + 2y = 13)

4x - 6y = 16
-15x + 6y = 39
Add the two equations.
-11x = 55
Divide each side by -11.
x = -5
