Given the inequality equation:
2a + 4 > 12
Solve for the inequality equation.
Solution:
In order to solve the given inequality, the first step is to transpose 4 on the other side of the equation. Hence we must take note that in transposing a number, the sign changes.
2a + 4 > 12
2a > 12 -4
2a > 8
Divide both sides by 2 in order to find the value of a.
a > 4
Final answer:
{a | a > 4}
