Question

geometry support unit 1 - introduction to geometry

1. given: ( 6x - 4 = 3x + 8 ).

prove: ( x = 4 )

Explanation:

Step1: Subtract \(3x\) from both sides

$$6x - 4-3x=3x + 8-3x$$
$$3x-4 = 8$$

Step2: Add \(4\) to both sides

$$3x-4 + 4=8 + 4$$
$$3x=12$$

Step3: Divide both sides by \(3\)

$$\frac{3x}{3}=\frac{12}{3}$$
$$x = 4$$

Answer:

\(x = 4\)
