Make 10 equations for 50,000

Kruka [31]

Answer:

1. 50 * 1,000 = 50,000

2. 49,001 + 999 = 50,000

3. 5 * 10,000 = 50,000

4. 100,000/2 = 50,000

5. 20,000 + 30,000 = 50,000

6. 50,000/1 = 50,000

7. 90,000 - 40,000 = 50,000

8. 10 + 49,990 = 50,000

9. 5,000 * 10 = 50,000

10. 1,000,000/20 = 50,000

Greetings!

Substitute:
$x+y=1000 \\ x=1000-y$
Now we can input this into the other equation so, we only have one variable.

Solve for y.
$0.05(1000-y)+0.06y=57$
Distribute the parenthesis.
$50-0.05y+0.06y=57$
Combine Like Terms.
$50-0.01y=57$
Add -50 to both sides.
$(50-0.01y)+(-50)=(57)+(-50)$
Simplify.
$0.01y=7$
Divide both sides by 0.01.
$(0.01y)/0.01=(7)/0.01$
Simplify.
$y=700$

Input this value into the other equation.
$x+700=1000$
Add -700 to both sides.
$(x+700)+(-700)=(1000)+(-700)$
Simplify.
$x=300$

The answer would be 300,700

Hope this helps.
