Question

Solve the inaquality 2(x-1)>8="2(x - 1) \geqslant 8" alt="2(x - 1) \geqslant 8" align="absmiddle" class="latex-formula">

Answer 1

2(x-1)≥8

1.  Divide both sides by 2 on the way towards isolating x on the left side:
     x-1 ≥ 4
2.  Add  1 to both sides to isolate x:     x≥5

That's it.  The solution set consists of all real numbers = to or greater than 5.
