GCSE Maths Practice: simultaneous-equations

Question 5 of 10

Solve simultaneous equations using elimination or addition method.

‹ ›

\( \begin{array}{l} \text{Select all correct solutions to the simultaneous equations:} \\ 2 \times x - y = 10 \quad (1) \\ x + y = 8 \quad (2) \end{array} \)

Select all correct options:

\( x = 6, y = 2 \) \( y = 2, x = 6 \) \( x = 3, y = 1 \) \( 6, 2 \)

Always verify solutions in both equations.

Adding or subtracting equations can remove one variable. Then substitute back to find the other.
