1. Write out your expression. You can treat inequalities like equalities when solving. This means if < or > make you uncomfortable, pretend it's an = and solve it algebraically:3p - 6 > 212. Add 6 to both sides.3p > 273. Divide by 3 on both sides.p > 94. P is greater than 9.
how to solve 7 + p = p +7
If: 6p-2-3p = 16 Then: p = 6
3p + 6p = (3 + 6)p = 9p
