Question

$$2.1 x + 6 = 14.4$$

Solve for x

$x=4$

Steps for Solving Linear Equation

Subtract $6$ from both sides.

$$2.1x=14.4-6$$

Subtract $6$ from $14.4$ to get $8.4$.

$$2.1x=8.4$$

Divide both sides by $2.1$.

$$x=\frac{8.4}{2.1}$$

Expand $\frac{8.4}{2.1}$ by multiplying both numerator and the denominator by $10$.

$$x=\frac{84}{21}$$

Divide $84$ by $21$ to get $4$.

$$x=4$$
