Question

Solve using substitution
6x + 2y = 0
4x + y = -1

Answer 1

start by solving the second equation \(4x+y=-1\) for \(y\) to get \(y=-1-4x\) then substitute in to first equation to get
\[6x+2(-1-4x)=0\] and solve that one

Answer 2

\[6x-2-8x=0\]\[-2x-2=0\]\[2x=-2\]
\[x=-1\] etc

Answer 3

thankyou so much !
