To solve the system of equations by substitution, we substitute the value of y from the second equation into the first equation.
Substituting y=3x into the first equation:
4x + (3x) = 14
7x = 14
Divide both sides by 7:
x = 2
Now, substitute the value of x into the second equation to find y:
y = 3(2)
y = 6
Therefore, the solution to the system of equations is x = 2 and y = 6.
Solve the system of equations by substitution.
4x+y=14
y=3x
