Answer:
The two equations are y=x+4 and y=2x+5.
Step-by-step explanation:
Given that (-1,3) is solutions of the system of two linear equations.
Let y=mx + c be the generalized equation of line having slope m and y-intercept c.
For different values of m and c, there are corresponding linear equations.
As the lines are passing through the point (-1,3), so, pot x=-1 and y=3 in the generalized equation, we have
All the real values of c and m which satisfy equation (i) are the desired linear equations.
As we required only two linear equations, take any two values of c and m.
For c=4 and m=1 (satisfying equation (i))
and for c=5, m=2
Hence, the two equations are y=x+4 and y=2x+5.

Answer:
x = 9
Step-by-step explanation:
Corresponding segments are proportional, so ...
(2x -8)/5 = (x -3)/3
3(2x -8) = 5(x -3) . . . multiply by 15
6x -24 = 5x -15 . . . . eliminate parentheses
x = 9 . . . . . . add 24-5x
6 5/6 is the correct answer
