Question

Solve the following systems of linear equations below by elimination or by substitution method. y = 4/3 x - 9

y = x + 3

Answer 1

x=33 and y=36

Explanation:

You can rewrite the equation into

x+2=4/3x-9

Now you can subtract 2 on both sides

x=4/3x-11

Now subtract 4/3x on both sides:

-1/3x=-11

Multiply -3 on both sides:

x=33

Now substitute x with 33

y=33+3

y=36

Thus x=33 and y=36

Hope this helps!
