Question

Use the method of substitution to solve the system of linear equations.

7x+4y=7/6
y=6x-1

Answer 1

just substitute y=6x-1 in the first equation
7x+4 (6x-1) = 7/6 solve for x then substitute for x in y=6x-1

Answer 2

I can't solve for x, thats the problem.

Answer 3

\[7x + 4(6x-1)= \frac{ 7 }{ 6}\]
\[7x+24x-4=\frac{ 7 }{ 6 }\]
\[31x = \frac{ 7 }{ 6 } + 4\]
\[31x = \frac{ 31 }{ 6 } * both sides \frac{ 1 }{ 31 }\]
\[x = \frac{ 1 }{ 6 }\]
\[y = 6 (\frac{ 1 }{ 6 }) -1 = 0\]

Answer 4
