Solve the system of equations 3x - 5y = 8 and -7x + 8y = -4 by combining the
equations

x = -4 and y = -4

Step-by-step explanation:

3x - 5y = 8

-7x + 8y = -4

Multiply first equation by 7;           21x - 35y = 56

Multiply second equation by 3;    -21x + 24y = - 12

Adding the equations we get

- 11y = 44

y = -4

3x - 5(-4) = 8

3x = 8 - 20; 3x = -12

x = -4

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
