GCSE Secondary Maths Age 13-17 - Algebra: Algebra - Explained

The video tutorial addresses an algebra problem involving three schools sending students to a revision day. Redlands School sends X students, St Samuel's sends twice as many, and Francis Long sends 7 fewer than Redlands. Each student pays £15, totaling £1155. The task is to determine the number of students each school sent. The solution involves setting up and solving equations, leading to the conclusion that Redlands sent 21 students, St Samuel's 42, and Francis Long 14. The video also explains the marks allocation for the problem.

What is the first step in solving the algebra problem presented in the video?

• Calculate the total cost of the revision day.

• Write the final statement of the solution.

• Identify the variables and understand the problem statement.

• Determine the number of students from each school.

How many times more students did St Samuel's School send compared to Redlands School?

• Half as many

• The same number

• Twice as many

• Three times more

What is the cost per student for attending the revision day?

• £10

• £20

• £25

• £15

What equation is formed to find the total number of students?

• X - 7 = 1155

• 2X + 7 = 1155

• 4X - 7 = 1155

• 3X + 7 = 1155

After simplifying the equation, what is the value of X?

• 28

• 14

• 42

• 21

How many students did Francis Long School send to the revision day?

• 28

• 42

• 14

• 21

What is the total number of students sent by all three schools?

• 77

• 91

• 84

• 63
