Question

How many solutions does the system of equations have y-5x=-6 and 3y-15=-12​

Answer 1

one solution

Explanation:

to understand this

you need to know about:

• system of linear equation
• PEMDAS

tips and formulas:

• a system of linear equation has only one solution if
  `(a_1)/(a_2)\\eq (b_1)/(b_2)`

let's solve:

define a,b

• 
  `a_1=1`
• 
  `a_2=3`
• 
  `b_1=-5`
• 
  `b_2=-15`

1. 
   `\sf substitute \: the \: value \: of \: a_1\: a_2 \: b_(1)\: b_(2) : \\ \sf (1)/(3) \\eq ( - 5)/( - 15) \\ \sf (1)/( 3) \\eq - (1)/(3)`

therefore

the system of linear equation has only one solution
