Use properties to rewrite the given equation. which equations have the same solution as x + + x = – x? check all that apply.
x + = – x
18x + 20 + 30x = 15 – 6x
18x + 20 + x = 15 – 6x
24x + 30x = –5
12x + 30x = –5

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.

5x−4≥12 or 12x+5≤−4 can you with this problem
