y - 50 = 32.1(x - 2) ‬    

y = 32.1x - 64.2 + 50 ‬       ‬‪

y = 32.1x - 14.2

Multiply out the brackets and add 50 to both side: y = 32.1x -64.2 +50

Simplify: y = 32.1x -14.2

Explaining the steps:

y - 50 = 32.1(x - 2)

Start with distributing the 32.1 into both terms on the right side of the equation:

y - 50 = 32.1x - 64.2Then add 50 to both sides to get "y" by itself on the left side of the equation:

y = 32.1x - 14.2

‪

y - 50 = 32.1(x - 2) ‬   

y = 32.1x - 64.2 + 50 ‬     

‬‪y = 32.1x - 14.2
