Graph both sides, then click the intersection. That point is the solution. Two lines, a line and a curve, y = a constant and a function: same click. Desmos access is in Desmos on the ACT.
What you are clicking
A system is two graphs. Their crossing is (x, y). A constant line y = k crossing a curve gives the x-values that solve f(x) = k, in graphing y equals a constant. Systems as algebra are in systems in Desmos.
If the crossing is off the screen, zoom out, in zooming a missing graph.
The bottom line
Two equations, two curves, one click on the crossing.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
