Which of the following represents the solution to the inequality -2x + 4 < 10?

Answer 1

Hey Adrian,

Operations (i.e., adding, subtracting, multiplying, dividing, etc.) on inequalities follow all the normal rules with one exception...

multiplying or dividing an inequality changes the direction of the inequality

Solve for x by isolating the variable on one side of the inequality sign:

-2x + 4 < 10

-2x + 4 - 4 < 10 - 4

-2x < 6

-2x ÷ -2 < 6 ÷ -2

x > -3

Hope this helps!
