Question

How many solutions does the following equation have ?

2y=5x+4
y=3x+2

Answer 1

You mean the following "system of equations?"

Answer 2

Do you know how to solve a system of equations?

Answer 3

ok cuz its "=" system of equation that mean there is exact sol , right ??
So its 2 equation wid two variables...
that mean one solution i guss ...

Answer 4

its gonna have two solutions , one for x and one for y

Answer 5

A system of two linear equations can have:
A) no solution, when the lines are parallel, and the system is inconsistent
B) one solution, when the lines intersect at one point, and the equations is independent
C) an infinite number of solutions, when the two equations are really one, so the lines are only one line, and the system is dependent.

Answer 6

^ trueeeeee ! i forgot bout all that

Answer 7

The way to find out how many solutions there are is to solve the system. Since the second equation is already solved for y, you can use the substitution method easily.
