Answer:

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
