A) \[8x+10y=25\]
B) \[2x+3y=7\]
C) \[7x+14y=17\]
D) \[12x+15y=45\]
Correct Answer: D
Solution :
For coincident lines, \[\frac{{{a}_{1}}}{{{a}_{2}}}=\frac{{{b}_{1}}}{{{b}_{2}}}=\frac{{{c}_{1}}}{{{c}_{2}}}\] i.e., \[\frac{4}{12}=\frac{5}{15}=\frac{15}{45}\] or \[\frac{1}{3}=\frac{1}{3}=\frac{1}{3}\]You need to login to perform this action.
