Question

What is g if, g + (g + 21) + (2g - 6) = 191

Answer 1

g=44

44+(44+21)+(2[44]-6)
44+(65)+(2[44]-6)
44+(65)+(88-6)
44+(65)+(82)
44+65+82
109+82=191

Answer 2

g=44

Explanation:

(2g+21) + (2g-6)=191

1. Eliminate redundant () :

2g+21+2g-6 =191

2. Subtract numbers:

2g+15+2g=191

Combine like terms:

4g+15=191

4g=176

Divide:

4g/4=146/4

Solve:

g=44
