Question

find the value of x in the given picture​

Answer 1

Answer:

(3x - 20 ⁰) + x = 100⁰

3x - 20⁰ + x = 100⁰

4x - 20⁰ = 100⁰

4x = 100⁰ + 20⁰

4x = 120⁰

x = 120⁰/ 4

x = 30⁰

3x = 3 × 30⁰

= 90⁰

x = 30⁰

Answer 2

Answer:

$= (3x - 20) + x = 180 \\ = 3x - 20 + x = 180 \\ = 4x - 20 = 180 \\ = 4x = 180 - 20 \\ = 4x = 160 \\ = x = 160 \div 4 \\ = x = 40$

hope it will help you
