Question

Ian solved the system of equations by making a substitution for y in the second equation.
what equation did he get the result of that substitution?
y= -3x+1
5x-2y=31

So you notice the first equation y is already solved for you, all you need to do is plug in that expression into the second equation as follow: $$\huge 5x-2\color{red}{(-3x+1)}=31$$

anonymous · Answer

the answer choices are: 
A) 5x+6x+1=31 
b) 5x+6x-2=31
c)-15x+5x=31
d)-15x-x=31

would the answer be B?

anonymous · Answer

what is the x coordinate of the solution to the systems of equations?
3x-2y=-30
6x+3y=3

anonymous · Answer

You can solve for one of the variables in one of the equations then do as we did above make a substitution and solve for x.
