Question

solve this system of equation using subtraction
8x - y = 4
5x + 3y = 17

Answer 1

you can do this.. right ??
refer to previous problem..

Answer 2

tbh no

Answer 3

ohkey understand this...

Multiply equation 1 by -3... (why -3 ?? because we can eliminate one variable..)

so -24x + 3y = -12... eqtn 1
5x + 3y = 17 ..... equation 2..

Now subtracting both of them..

-29x = -29..

so x = 1... substitute the value in any of the equation above..

5(1) + 3y = 17
3y = 12

y = 4..

Now you understand, and u should know... right ??
