Graph the left side as one function and the right side as another. The x-coordinate of the intersection is the solution. Desmos as a tool is in Desmos on the ACT.
Two lines, one click
2x + 1 = 7 becomes y = 2x + 1 and y = 7. Click the crossing. No crossing can mean no solution. Intersections as a set are in find intersections.
Two graphs that sit on top of each other are equivalent, in equivalent expressions.
The bottom line
Split the equation. Click the intersection. That x is the answer.
