Answer:

Option 1 - Using the Subtraction Property of Equality, 2 is subtracted from both sides of the equation.          

Step-by-step explanation:

Given : Process

Step 1: 4x + 2 = 10

Solve the equation thanks!
AlladinOne [14]

Answer:

c = \frac{27}{40}

Step-by-step explanation:

To eliminate the fractions, multiply all terms by the lowest common multiple of 8 and 5

The lowest common multiple of 8 and 5 is 40

5 + 40c = 32 ( subtract 5 from both sides )

40c = 27 ( divide both sides by 40 )

c = \frac{27}{40}
