What’s the solution of y= 3x-1 and y= 3x+4

julia-pushkina [17]

Step-by-step explanation:

solution ? you mean where both lines cross each other ?

these are 2 parallel lines (same slope, but different y-intercept), so they never cross each other.

there is no solution.

formally :

3x - 1 = 3x + 4

-1 = 4

this is wrong. therefore there is no solution.
