Answer the answer is x equals 65 - 60 y. step-by-step explanation: Now, let ‘ X’ Years be the age of Raul’s sister Paula. Also, given the following information - Raul’s age equal grandfather's age - 60 * the sisters age since the age of Miguel, Raul’s grandfather is 65 years so we can write the following equation to find Paula’s age

x =65 - 60 x y

60y=65-x

y= 65-x/60

Thus, we can find Paula’s age (y) using the equation

y=65-x/60 where ‘x’ is the age of Raul
Rewrite the equation from Part D by factoring the side that contains the variable p.

c is the answer

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
