What is the value for x 3x - 2 = 16

18

Step-by-step explanation:

I meant 6x3=18 -2=16 sorry for confusion

To find the value of x, you need to isolate/get the variable "x" by itself in the equation:

3x - 2 = 16       Add 2 on both sides

3x - 2 + 2 = 16 + 2

3x = 18         Divide 3 on both sides to get "x" by itself

x = 6

PROOF

3x - 2 = 16      Substitute/plug in 6 into "x" since x = 6

3(6) - 2 = 16

18 - 2 = 16

16 = 16

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
