The number of puplis is an illustration of linear equations , and there are 18 boys and 9 girls in the class
How to determine the number of boys and girls?
The given parameters are:
Total = 27
Boys (b) = 2 * Girls (g)
So, we have:
b + g = 27
b = 2g
Substitute b = 2g in b + g = 27
2g + g = 27
Evaluate
3g = 27
Divide both sides by 3
g = 9
Substitute g = 9 in b = 2g
b = 2 * 9
Evaluate
b = 18
Hence, there are 18 boys and 9 girls in the class
