Solve {l}{5j--145=700}{k=j}{text{Solvefor}ltext{where}}{l=k}

$$\left. \begin{array} { l } { 5 j - -145 = 700 }\\ { k = j }\\ { \text{Solve for } l \text{ where} } \\ { l = k } \end{array} \right.$$

Solve for j, k, l

$$l=111$$

Solution Steps

Consider the first equation. The opposite of -145 is 145.

$$5j+145=700$$

Subtract 145 from both sides.

$$5j=700-145$$

Subtract 145 from 700 to get 555.

$$5j=555$$

Divide both sides by 5.

$$j=\frac{555}{5}$$

Divide 555 by 5 to get 111.

$$j=111$$

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

$$k=111$$

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

$$l=111$$

The system is now solved.

$$j=111 k=111 l=111$$
