Reformatting the input :

Changes made to your input should not affect the solution:

(1): "4.5" was replaced by "(45/10)".

Rearrange:

Rearrange the equation by subtracting what is to the right of the less equal sign from both sides of the inequality :

-3*(-2*w-6)-(10-2*(-2*w-(45/10)))≤0

Rewriting the whole as an Equivalent Fraction

2.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using 2 as the denominator :

-2w -2w • 2
-2w = ——— = ———————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-2w • 2 - (9) -4w - 9
————————————— = ———————

Pulling out like terms :

6.1 Pull out like factors :

-2w - 6 = -2 • (w + 3)

:

8.1 Divide both sides by 2

w-(1/2) ≤ 0


Solve Basic Inequality :

8.2 Add 1/2 to both sides

w ≤ 1/2
