Question

Example 2: Find the value of x. (3x - 9) (x + 35), somebody pls help a brotha wit dis

Answer 1

Answer:

x = 22

Step-by-step explanation:

Both angles shown correspond to the same point in the two triangles, so they are the same.

Put these expression into an equation like this: 3x - 9 = x + 35

3x - 9 = x + 35

Subtract x from both sides.

3x - 9 - x = 35

Subtract x from 3x to get 2x.

2x - 9 = 35

Add 9 to both sides

2x - 9 + 9 = 35 + 9

Add 35 and 9 to get 44. -9 and 9 cancel each other out

2x = 44

Divide both sides by 2.

2x/2 = 44/2

x = 44/2

Divide 44 by 2 to get 22.

x = 22

Check your work if it works

3(22) - 9 = 22 + 35

66 - 9 = 57

57 = 57

Both sides equal each other, so x is 22.
