Answer:

x = 1.2375 or 99/90

Step-by-step explanation:

Step 1: Distribute

21 + 40(2x - 3)

21 + 80x - 120

Step 2: Combine like terms

21 + 80x - 120

80x - 99

Step 3: Solve for x

80x - 99 + 99 = 0 + 99

80x / 80 = 99 / 80

x = 1.2375

Answer: x = 1.2375 or 99/80

$\text {Hi! To solve this problem you must...}$

$\text {Do Keep Change Flip (KCF):}$

$\text {Keep: -3/8}$

$\text {Change: / into *}$

$\text {Flip: 1/2 into 2/1}$

$\text {Your new problem should be -3/8*2/1}$

$\text {The Final Step is to Multiply:}$

$\text {Note: When Multiplying Fractions you multiply Numerator by Numerator}$

$\text {and Denominator by Denominator}$

$\text {-3/8*2/1=}$

$\fbox {-6/8}$

$\text {Best of Luck!}$
