Question

Solve the following system of equations for y.

2x + 6y = 230
12x - 7y = 90

Answer 1

I love you

Answer 2

no you dont

Answer 3

2x + 6y = 230-----(1)
12x - 7y = 90-----(2)

in equation (1)

\[2x + 6y = 230\]

\[y =\frac{ 230-2x }{ 6 }\]

put y in equation (2)

\[12x - 7(\frac{ 230-2x }{ 6 }) = 90\]

\[12x-\frac{ 1610+14x }{ 6 }=90\]

\[72x-1610+14x=540\]

\[86x=2150\]

\[x=25\]

put x in equation (1)

\[2x + 6y = 230\]

\[2(25) + 6y = 230\]

\[6y=180\]

\[y=30\]

Answer 4

incorrect

Answer 5

sorry you just waisted your time
