CCSS 7.EE.B.4a · px + q = r and p(x + q) = r
Generate equations directly from the two forms named in 7.EE.B.4a. Solutions are constructed first and the equation is built around them, so rational coefficients remain exact and every answer can be verified by substitution.

For px + q = r, undo q before dividing by p.
For p(x + q) = r, divide by p first, then undo q inside the parentheses.
Check the solution by substitution into the original equation, not only into an intermediate line.

Yes. Standard and challenge modes can include rational coefficients and rational solutions.
No. This route stays with the equation forms named in Grade 7 standard 7.EE.B.4a rather than drifting into later algebra.
