What are simultaneous linear equations?

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

here,
Let the number of phone sales be x and the number of computer sales be y,
According to the question,
0.09x+0.06y=135, - - - - - (1}
x+y=1700 - - - - - - - (2)
Solving equation 1 and 2
Gives, x = $1100 and $600

Thus, the required amount for phone and computer sales is $1100 and $600 respectively.
