Question

Solve the system of linear equations by substitution. Check your solution.
3x=y-10
x-6=y

Answer 1

3x= y-10 ............(1)
X-6=y ..................(2)ing
Putting value of y equation (1)
We get
3x=x-6-10
3x-x = -16
2x = -16
X = -8
Putting value of x in epuation (2)
We get,
-8-6= y
Y =-14 Ans

Answer 2

$3x - y = - 10 \\ x - y = 6 \\ now \:adding \\ 2x = - 4 \\ x = - 4 \div 2 \\ x = - 2 \\ now \: subsitute \: the \: value \: in \: eq. \:2 \: \\ ( - 2) - y = 6 \\ - y = 6 + 2 \\ - y = 8 \\ y = - 8 \\ therefore \: the \: ans. \: is \: x = - 2and \: y = - 8 \\ thi \: i \: your \: s \\ answer \:$
