Imagine he second side is x so the first side is (x-3) and the third side is (x+4)
So x + (x-3) + (x+4) = 34
3x+1 = 34
3x=33
X=11
So longest side is (x+4) so 11+4=15

Please help me to find the answer Y=2X 3X+4Y=22 Y=2X 3X+4Y=22 ​
RSB [31]
<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}
