If b = the number of boys, which alg expression represents the phrase. The sum of the number of boys and 15 girls is b+15.
Always solve equations for such questions using the information provided in the question. Then, as stated in the solution, we may locate the two unknown variables using the two equations that were created.
This kind of question can be answered by assuming any two numbers, x and y, and then applying the condition specified in the question. We know quite well that any equation that can be written in the form ax+by+c=0, where a, b, and c are real integers, and a and b are not zero, is known as a linear equation in two variables. When we apply the condition, we obtain two linear equations with two variables.
Given that the number of boys is b,
Number of girl = 15 girls
Thus the sum of noys and girls is b+15.
