For a given equation if the value of a variable is unknown, then the equation is solved

in order to find the value of the variable.

Different algebraic operations are used in order to solve the given equation.

Subtract 12 on both sides of the equation.

4x +12 -12 = 36 -12

4x = 24

Now, divide by 4 on both sides of the equation.

4x/4 = 24/4;

**x = 6**

**Hence the value of the unknown variable x is 6**

Now, divide by 4 on both sides of the equation.

4x/4 = 24/4;

To solve the given expression, plug in the values of x = 2, y = 3 and z = 2 in the equation

5x + 2y + 3z.

This gives us 5*2 + 2*3 - 3*2 = 10 + 6 -6 = 16 - 6 = 10.
