Answer:

x = 20

Step-by-step explanation:

Angle 2 and Angle 5 are corresponding angles

Corresponding angles are congruent

If angle 2 = 3x - 20 and angle 5 = x + 20

Then 3x - 20 must equal x + 20 ( because corresponding angles are congruent )

Notice that weve just created an equation that we can use to solve for x

We now solve for x using the equation we created

3x - 20 = x + 20

Step 1 add 20 to both sides

3x = x + 40

Step 2 Subtract x from both sides

2x = 40

Step 3 divide both sides by 2

x = 20

What is the answer for 8x+3=4x?

AysviL [449]

Answer:

x = -3/4

Step-by-step explanation:

Step 1: Identify the equation

8x + 3 = 4x

Step 2: Move x's to one side and number to the other side

8x + 3 - 4x - 3 = 4x - 4x - 3

4x = -3

Step 3: Make x by itself

4x / 4 = -3 / 4

x = -3/4

Answer: x = -3/4
