Answer:
one solution
Step-by-step 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 [tex]\frac{a_1}{a_2}\neq \frac{b_1}{b_2}[/tex]
let's solve:
define a,b
- [tex]a_1=1[/tex]
- [tex]a_2=3[/tex]
- [tex]b_1=-5[/tex]
- [tex]b_2=-15[/tex]
- [tex] \sf substitute \: the \: value \: of \: a_1\: a_2 \: b_{1}\: b_{2} : \\ \sf \frac{1}{3} \neq \frac{ - 5}{ - 15} \\ \sf \frac{1}{ 3} \neq - \frac{1}{3} [/tex]
therefore
the system of linear equation has only one solution
