<h3>System of equations.</h3>

\left\{\begin{array}{ccc}y=2x&(1)\\3x+4y=22&(2)\end{array}\right

Put (1) to (2):

3x+4(2x)=22\\3x+8x=22\\11x=22\qquad|\text{divide both sides by 11}\\\boxed{x=2}

Substitute the value of x to (1):

y=2\cdot2\\\boxed{y=4}

Solution:

\huge\boxed{\left\{\begin{array}{ccc}x=2\\y=4\end{array}\right}
