Question

Solve the following inequations
a) 4-2x = 10
b) x+3>-2x​

Answer 1

x = -3

-1 < x

Explanation:

a) 4-2x = 10

Subtract 4 from each side

4-4-2x = 10-4

-2x = 6

Divide each side by -2

-2x/-2 = 6/-2

x = -3

b) x+3>-2x​

Subtract x from each side

x+3-x > -2x-x

3 > -3x

Divide each side by -3, remembering to flip the inequality

3/-3 < -3x/-3

-1 < x
