Question

(3x+15)° =150 then value of x

Answer 1

Answer :-

• Value of x is 45.

Given :-

• An equation (3x+15)° = 150

To Find :-

• Value of x

Solution :-

⇒ 3x + 15 = 150

→ Write the equation first

⇒ 3x = 150 - 15

→ Move 15 to right and "+" sign will be changed into "-" sign

⇒ 3x = 135

→ Subtract 15 from 150

⇒ x = 135/3

→ Divide 135 by 3

⇒ x = 45

Hence, the value of x is 45.

Answer 2

Step-by-step explanation:

Given Equation:-

(3x+15)°=150

Required Solution:-

• First remove the brackets.

${:}\dashrightarrow$$\sf {3x+15=150}$

• Now interchange both sides
• Take 15 to the right side by which the "+"sign will turn "-"sign

${:}\dashrightarrow$$\sf {3x=150-15}$

${:}\dashrightarrow$$\sf {3x=135}$

• Now Take 3 to the right side by which the the "×"sign will turn "÷"

${:}\dashrightarrow$$\sf {x={\dfrac {135}{3}}}$

${:}\dashrightarrow$${\underline{\boxed{\sf {x=45°}}}}$
