Solve {l}{5X+X=30}{a=X}{b=a}{c=b}{text{Solvefor}dtext{where}}{d=c}

$$\left. \begin{array} { l } { 5 X + X = 30 }\\ { a = X }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Solve for X, a, b, c, d

$$d=5$$

Solution Steps

Consider the first equation. Combine 5X and X to get 6X.

$$6X=30$$

Divide both sides by 6.

$$X=\frac{30}{6}$$

Divide 30 by 6 to get 5.

$$X=5$$

Consider the second equation. Insert the known values of variables into the equation.

$$a=5$$

Consider the third equation. Insert the known values of variables into the equation.

$$b=5$$

Consider the fourth equation. Insert the known values of variables into the equation.

$$c=5$$

Consider the fifth equation. Insert the known values of variables into the equation.

$$d=5$$

The system is now solved.

$$X=5 a=5 b=5 c=5 d=5$$
