Mathematics for IGCSE & O level - Equations (Section 1 - No. 30)
The sum of two numbers is 10, and their difference is 4. Write a system of equations to solve this.
x + y = 10, x - y = 4
x - y = 10, x + y = 4
2x = 10, 2y = 4
x + y = 4, x - y = 10
Explanation
x+y represents sum, x-y represents difference
