What is the answer to the problem 21+40(2x-3)
12345 [234]

Answer:

x = 1.2375 or 99/90

Step-by-step explanation:

<u>Step 1:  Distribute</u>

21 + 40(2x - 3)

21 + 80x - 120

<u>Step 2:  Combine like terms</u>

21 + 80x - 120

80x - 99

<u>Step 3:  Solve for x</u>

80x - 99 + 99 = 0 + 99

80x / 80 = 99 / 80

x = 1.2375

Answer:  x = 1.2375 or 99/80
