Question

(3x - 10) : 10 = 2³

Answer 1

\(\left(3x-10\right):10=2^3\)

\(\left(3x-10\right):10=8\)

\(3x-10=8.10\)

\(3x-10=80\)

\(3x=80+10\)

\(3x=90\)

\(x=90:3\)

\(x=30\)

Answer 2

(3x - 10) : 10 = 2³

(3x - 10) : 10 = 8

3x - 10 = 8.10

3x - 10 = 80

3x = 80 + 10

3x = 90

x = 90 : 3

x = 30

Answer 3

(3x-10):10=2³

^(3x-10):10=8

^3x-10=8x10

3x-10=80

3x=80+10

3x=90

x=90:3

x=30
