Question

solve the inequality 4-x>-2


answer correctly​

Answer 1

Answer:

x < 6

∴ -x > -2 - 4

∴ -x > -6

∴ x < 6

Answer 2

Step-by-step explanation:

Example 1 Solve for x and check: x + 5 = 3

Solution

Using the same procedures learned in chapter 2, we subtract 5 from each side of the equation obtaining

Example 2 Solve for x and check: - 3x = 12

Solution

Dividing each side by -3, we obtain

Always check in the original equation.

Another way of solving the equation

3x - 4 = 7x + 8

would be to first subtract 3x from both sides obtaining

-4 = 4x + 8,

then subtract 8 from both sides and get

-12 = 4x.

Now divide both sides by 4 obtaining

- 3 = x or x = - 3.
