6 0

$5n + 5w = r \\ \\ 5n = r - 5w \\\\ n = \frac{r-5w}{5}$

3 0

R = 5n + 5w
r - 5w = 5n
r/5 - w = n

Given: ${x}^{2} - 7x + 7y - {y}^{2}$

Now factoring them,

$= > (x - y)(x + y) - 7(x - y)$

$= > (x - y)(x + y - 7)$

Therefore, the answer to the question is $(x - y)(x + y - 7)$

Multiply 2nd equation by 3 and add to first
9x-3y=-2
-9x+3y=-9 +
0x+0y=-7

0=-7
false
no solution

$\frac{x^\frac{1}{2} }{x^\frac{2}{7}}$

According to the rule of exponents $\frac{a^m}{a^n} = a^{(m-n)}$ , i.e. when two terms are in division with same base , we subtract the exponents

$\frac{x^\frac{1}{2} }{x^\frac{2}{7}} = x^{(\frac{1}{2}) - (\frac{2}{7})}$

$=x^\frac{3}{14}$

x to the 3 fourteenths power
