Equations such as 3𝑥 + 8 = 15 need two steps. Make sure you are confident in calculating with negative numbers, which is a skill often needed to solve equations.

algorithms New Algorithm Breaks Speed Limit for Solving Linear Equations By harnessing randomness, a new algorithm achieves a fundamentally novel — and faster — way of performing one of the most basic ...

This study evaluated students' representational choices while they solved linear function problems. Eighty-six secondary-school students solved problems under one choice condition, where they chose a ...
