Answer:
x =
Step-by-step explanation:
3(2x - 3) + 4(2 - x) = 0 ← distribute parenthesis
6x - 9 + 8 - 4x = 0 , that is
2x - 1 = 0 ( add 1 to both sides )
2x = 1 ( divide both sides by 2 )
x =
Answer: x≤ -0.5
Step-by-step explanation: Graph the two lines or solve for x:
2x – 6 ≥ 6(x – 2) + 8
2x – 6 ≥ 6x – 12 + 8
2x – 6 ≥ 6x – 4
-4x ≥ 2
x ≤ -1/2 [Inequality is reversed when multiplying or dividing by a negative number]
The number line is anything less than or equal to - 1/2
Or one can plot each side of the inequality and note the interception point (x = -(1/2)).
