Y= 3x + 1
Alika [10]

Answer:

y= -11

Step-by-step explanation:

After rearranging equation 2, we get x= y+3/2

Sub it into equation 1

y= 3(y+3/2) + 1

y= 3y+9/2 + 1

y= 3y + 11 / 2

2y = 3y + 11

-y = 11

y = -11

Answer:

a) y = 6x - 3

b) 1/3y = 2x -1

The first thing you need to do is isolate (y) in the second equation

3 x (1/3y) = 3 x (2x - 1)

y =6x - 3

After isolating (y) in equation b they end up being the same.

Graphing:

In order to graph this, you have to make the first point at (0, -3) since this is the Y-intercept of the equation.

In order to graph the other points, you must move 6 units up and 1 unit to the right. Or vise versa If you need a visual I'll gladly link one.
