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

Answer:
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
