paxpolaris · Answer

@Ty413 by addition method do you mean: 
solving the simultaneous equations by adding or subtracting them to get rid of 1 variable

paxpolaris · Answer

?

here you can subtract the second equation from the first and get rid of the y

YES IM HERE SORRY

anonymous · Answer

can you just solve the problem

paxpolaris · Answer

x-(-2x)  = 3x
y-y        =  0
4-1       = 3

so subtract 2nd equation from 1st, we get: $$\Large 3x=3$$$$\implies \Large x=1$$

paxpolaris · Answer

next plug x=1 in either equation to solve for y

paxpolaris · Answer

$$\Large 1+y=4$$$$\implies\Large y=3$$

so x=1, and y=3
