Question

20 - 3(3x - 4) Solve the equation

Answer 1

Answer:

32 - 9 x (don't know what you want simplify or solve for x) x = 32/9

Step-by-step explanation:

Simplify the following:

20 - 3 (3 x - 4)

-3 (3 x - 4) = 12 - 9 x:

12 - 9 x + 20

Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:

(20 + 12) - 9 x

20 + 12 = 32:

Answer: 32 - 9 x

_________________________________

Solve for x:

20 - 3 (3 x - 4) = 0

-3 (3 x - 4) = 12 - 9 x:

12 - 9 x + 20 = 0

Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:

(20 + 12) - 9 x = 0

20 + 12 = 32:

32 - 9 x = 0

Subtract 32 from both sides:

(32 - 32) - 9 x = -32

32 - 32 = 0:

-9 x = -32

Divide both sides of -9 x = -32 by -9:

(-9 x)/(-9) = (-32)/(-9)

(-9)/(-9) = 1:

x = (-32)/(-9)

Multiply numerator and denominator of (-32)/(-9) by -1:

Answer: x = 32/9
