A student is solving the equation 10x−3+2x=6(x−3). Which describes a first step the student could use to solve the equation corr
Arisa [49]

Students can combine like terms on the left side of the equation, resulting in 12x−3=6(x−3).

Given the equation solved by a student

10x−3+2x=6(x−3)

  • The first step that the student could use to solve the expression correctly is to expand the bracket on the right-hand side of the equation using the distributive law as shown:

10x-3+2x=6(x-3)\\10x-3+2x=6x - 6(3)\\10x-3+2x=6x - 18\\

  • The student can also combine like terms on the left side of the equation, to give;

10x-3+2x=6(x-3). \\10x+2x-3=6(x-3)\\12x-3=6(x-3)

Hence the correct option will be students can combine like terms on the left side of the equation, resulting in 12x−3=6(x−3).
