Solve the system of linear equations in three variables. 4x +y – 2z = 0
2x – 3y + 3z = 9
-6x-2y+z = 0

A. (-2, 1/2, 3/4)
B. (1/2, 3/4, -2)
C. (-2, 3/4, 1/2)
D. (3/4, -2, 1/2)

if you mean

then it's c. 8, -7/3

but if you mean

then it is

i agree because i see the other persons thinking is clear

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
