Question

Select three equations that could represent a step in solving this system using the substitution method. 4x+y = 6 x = 8 0.00 0:52 9 1x 2 4(8)+y=6 o y = 18

Answer 1

`\begin{gathered} 4x+y=6 \\ x=8 \end{gathered}`

the first step is replacing x=8 on the first equation, so

`4(8)+y=6`

the second step is do the multiplication

`\begin{gathered} 32+y=6 \\ y+32=6 \end{gathered}`

and the last step is place the 32 on the other side substracting

`\begin{gathered} y=6-32 \\ y=-26 \end{gathered}`
