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

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
