Question

(3x-1)+31+90=180 Find x

Answer 1

SOLVE FOR X

ANSWER:

x = 20

• Add −1 and 31 to get 30.

$\large\color{orange}{ \tt{3x+30+90=180}}$

• Add 30 and 90 to get 120.

$\large\color{orange}{ \tt{3x+120=180}}$

• Subtract 120 from both sides.

$\large\color{orange}{ \tt{3x=180−120}}$

• Subtract 120 from 180 to get 60.

$\large\color{orange}{ \tt{3x=60}}$

• Divide both sides by 3.

$\large\color{orange}{ \tt{x=60/3}}$

• Divide 60 by 3 to get 20.

$\large\color{orange}{ \tt{x = 20}}$
