What is the value of the x and the y? -3x-7y=-63

PIT_PIT [208]

Step-by-step explanation:

-3x - 7y = -63

-(3x + 7y) = -63

3x + 7y = -63/-1

3x + 7y = 63

Value of x

3x + 7y = 63

3x = 63 - 7y

x = (63 - 7y)/3

Value of y

3x + 7y = 63

7y = 63 - 3x

y = (63 - 3x)/7

<h2>Answer = </h2><h2> $= \frac{1}{y {}^{5} x {}^{2} }$ </h2>

Step-by-step explanation:

Greetings !

simplify for variable y first

apply exponent rule

$a {}^{b} .a {}^{c} = a {}^{b +c \\ } \\ y {}^{ - 8}y {}^{5} = y {}^{ - 8 + 3}$

Add/subtract the numbers -8+3=5

$= y {}^{5}$

Apply exponent rule

$a {}^{ - b} = \frac{1}{a {}^{b} }$

Thus,

$y {}^{ - 5} = \frac{1}{y {}^{5} }$

secondly, simplify for the variable x

Apply exponent rule as we made on y

$x {}^{ - 2}$

$x {}^{ - 2} = \frac{1}{x {}^{2} }$

multiply bot the values we get

Hope it helps!
