Easy
Solve the pair of linear equations for x: 1x + 5y = 11 and 5x + -4y = 26.
Explanation
Explanation
Using the elimination method: multiply the first equation by -4 and the second by 5, then subtract to eliminate y. Solving gives x = 6 (and correspondingly y = 1). You can verify: 1(6) + 5(1) = 11 ✓ and 5(6) + -4(1) = 26 ✓.
PRO TIP
Re-check your working by substituting the answer back into the original question.
