Solve 3 (3 - 3x) +4= -5.

x=2

Step-by-step explanation:

3 (3 - 3x) +4= -5

Subtract 4 from each side

3 (3 - 3x) +4-4= -5-4

3 (3 - 3x)= -9

Divide by 3

3/3 (3 - 3x) = -9/3

3-3x = -3

Subtract 3 from each side

3-3x-3 = -3-3

-3x = -6

Divide by -3

-3x/-3 = -6/-3

x = 2

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
