We can use the first equation to substitute y in the second equation:
x + (1/3)(3x+4) = 4/3
Simplifying:
x + x + (4/3) = 4/3
2x = 0
Therefore, x = 0. We can use this value of x to find y using the first equation:
y = 3(0) + 4
y = 4
Thus, the solution to the system of linear equations is (0,4).
Use substitution to solve the system of linear equations. In your final answer, include all of your work.
{y=3x+4
{x+1/3y=4/3
