3 * 2 equals 6, 2 * 3 equals 6, 6 - 6 is 0 + 6 equals 6. I really don't know I'm pretty I may be wrong but here's a thought.
Answer:

• Distributive property

• Addition property of equality

• Division property of equality

• Solution:

The solution is (-4,4)
Step-by-step explanation:
Given equations are:

In linear combination method, we have to make coefficients of any one variable opposites by multiplying with an integer
So multiplying 2nd equation by -2

Adding Equation 1 and Equation 3:

Dividing both sides by 3

Putting y=-4 in equation 1

Dividing both sides by 4

Hence,
The solution is (-4,4)

Answer:
3/2
Step-by-step explanation:
Given y = 2x + 5, let's rewrite the equation in terms of x;
y = 2x + 5 => Bring 5 to the other side
2x = y - 5 => Divide either side by 2
x = (y - 5)/2
If we want to take the inverse, simply swap the variable's positions...
We have y = (x - 5)/2
Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1
f^-1(8) = (8 - 5)/2 = 3/2
Solution: 3/2
O=oil painting's age
w=water color's age
o=16+w
o=3w
subsitute
3w=16+w
minus w both sides
2w=16
divide by 2
w=8
