•a unique solution
•infinitely many solutions
•no solution
•two solutions

Please answer this question fast​

Answer 1

Answer:

Unique Solution

Step-by-step explanation:

Condition for unique solution :- $\frac{a_1}{a_2}$ $\neq$ $\frac{b_{1} }{b_{2}}$

Condition for infinitely many solutions :- $\frac{a_{1} }{a_{2} }$ = $\frac{b_{1} }{b_{2} }$ = $\frac{c_{1} }{c_{2} }$

Condition for no solution :- $\frac{a_{1} }{a_{2} }$ = $\frac{b_{1} }{b_{2} }$ $\neq$ $\frac{c_{1} }{c_{2}}$

∴ 3x - 5y = 7

  6x + 10y = 7

$\frac{3}{6}$ $\neq$ $\frac{-5}{10}$

$\frac{1}{2}$ $\neq$ $-\frac{1}{2}$

∴ The pair of equations has a unique solution...
