KS2 Primary Maths Age 9-13 - Equations: - Explained

The video tutorial explains how to solve a system of two equations to find the value of Y. It begins by introducing the equations: 8 = X + 3 and Y + 2 = 10 + X. The instructor first solves for X using the first equation, finding X = 5. This value is then substituted into the second equation to solve for Y, resulting in Y = 13. The tutorial emphasizes the importance of each step in the process, highlighting the marks awarded for finding X and substituting it correctly.

What is the main objective when given the equations 8 = X + 3 and y + 2 = 10 + X?

• To find the value of Z

• To find the value of Y

• To find the value of both X and Y

• To find the value of X

How do you determine the value of X from the equation 8 = X + 3?

• Multiply 8 by 3

• Add 3 to 8

• Divide 8 by 3

• Subtract 3 from 8

What is the value of X when solving the equation 8 = X + 3?

• 3

• 10

• 5

• 8

After finding X = 5, what is the next step to solve for Y in the equation y + 2 = 10 + X?

• Add 5 to both sides

• Subtract 5 from both sides

• Substitute X with 5

• Multiply both sides by 5

What is the final value of Y when solving the equation y + 2 = 10 + X with X = 5?

• 15

• 13

• 12

• 10
