What is the solution of 3x + 5 = 2x – 7?
the x-coordinates of the intersection point of the lines y = 3x + 5 and y = 2x – 7
the x-coordinates of the x-intercepts of the lines y = 3x + 5 and y = 2x – 7
the y-coordinate of the intersection point of the lines y = 3x + 5 and y = 2x – 7
the y-coordinates of the y-intercepts of the lines y = 3x + 5 and y = 2x – 7
It's the first choice. If we solve the simultaneous system
y = 3x + 5
y = 2x – 7
the x coordinate (there's only one) of the meet of the two lines tells us the value of x which satisfies 3x+5=2x-7
