- 3x − 4 = 11 → 3x = 15 → x = 5
- 3x − 4 = 11 = x = 5
- x/2 + 7 = 10 = x = 6
- −2x + 9 = 1 = x = 4
- 5 − x = 2 = x = 3
- Common mistake: 3x − 4 = 11 → divide by 3 first → add 4 first
Substitute your answer back into the original equation. Every time.

- Who is the Two-Step Equations poster for?
- Two-Step Equations is filed under 7th Grade (ages 12–13), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Two-Step Equations poster?
- Ask what happened to x last. Undo that first. A wall chart earns its place by being glanceable from where the work is happening, so Two-Step Equations belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Two-Step Equations?
- Variables on Both Sides, Angle Pairs and Area of a Circle sit alongside Two-Step Equations in the 7th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Variables on Both SidesAngle PairsArea of a Circle
- Is the Two-Step Equations poster free to download and print?
- Yes. Two-Step Equations downloads as a free PDF with no account, no email and no watermark, like everything else in the 7th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Two-Step Equations poster print at?
- Two-Step Equations is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Two-Step Equations loses nothing.Printing guide
