GCSE Maths Practice: simultaneous-equations

Question 4 of 10

Solve simultaneous equations using elimination or addition method.

‹ ›

\( \begin{array}{l} \text{Select all correct solutions to the simultaneous equations:} \\ 2 \times x + y = 7 \quad (1) \\ 3 \times x - y = -2 \quad (2) \end{array} \)

Select all correct options:

\( x = 1, y = 5 \) \( y = 5, x = 1 \) \( 1, 5 \) \( x = 2, y = 4 \)

Check each solution in both equations to verify correctness.

Adding equations can eliminate one variable. Then substitute back to find the other.
