Solve each EQUATION.
Three times the difference of a number and 2 is 15

The number is 7

Step-by-step explanation:

Let x be the unknown number

difference is subtraction and is means equals

3 ( x-2) = 15

Divide each side by 3

3/3(x-2) = 15/3

x-2 = 5

Add 2 to each side

x-2+2 = 5+2

x = 7

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
