<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:

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

A 6500 gallon storage tank is 2/13 full of oil. How many gallons of oil are in the tank

user100 [1]

The gallons of oil in the tank is 1000

A 6500 gallon storage tank is 2/13 full

The number of oil in the tank can be calculated by multiplying the amount of gallons in the tank which is 6500 by the measurement of the tank which is 2/13

= 2/13 × 6500

= 13,000/13

= 1,000

Hence 1000 gallons of oil are in the tank
