Question
Solve the equation 2y - 1 = y + 1 and represent it graphically on the coordinate plane.
✓
Answer
We are given,
2y - 1 = y + 1
we get,
2y - y = 1 + 1
y = 2
The representation of the solution on the Cartesian plane, it is a line parallel to y axis passing through the point (0, 2) is shown below
2y - 1 = y + 1
