Question

Does anyone know how to do this? And can you also help me with this problem, thank you :)

How would you do this problem or does it need to be switched? Please show me.
4x-3y=33
x=-4y-25

Answer 1

Multiply equation(2) with 4 so that coefficient of become same in both the equations(You can make coefficient of y same and can follow the following procedure.)
* Subtract (3) from (1)
* Divide both sides by -19
*Subtract 21 from both sides.
*Divide both sides by 4
so the solution is x= 3 and y= -7
Hope I helped you :)
