Answer:

<em>The values are a=6, b=8</em>

Step-by-step explanation:

The following system of equations

ax - by = 4

bx - ay = 10

Has the solution x=2, y=1. Substituting:

2a - b = 4 [1]

2b - a = 10 [2]

Multiply [1] by 2:

4a - 2b = 8

Add with [2]:

3a = 18

a = 18/3 = 6

a = 6

From [1]:

2*6 - b = 4

b = 12 - 4

b = 8

The values are a=6, b=8

When you divide with negative exponents, you divide the rational numbers like normal and then you add the exponents.

Doss [256]

Answer:

the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.
