Question

Solve for x.
2.8 + 2x
8
=
0.6
x = [?]

Answer 1

x = 1

Explanation:

Step 1: Multiply both sides by 8.

• 
  `(2.8+2x)/8 * 8 = 0.6 * 8`
• 
  `2.8 + 2x = 4.8`

Step 2: Subtract 2.8 from both sides.

• 
  `2.8+2x-2.8=4.8-2.8`
• 
  `2x=2`

Step 3: Divide both sides by 2.

• 
  `2x/2 = 2/2`
• 
  `x=1`

Therefore, x = 1.

Answer 2

2.8 + 2x = 0.6

______

8

multiply by 8 to both sides

x8 x8

2.8 + 2x = 4.8

subtract 2.8 from both sides

-2.8 -2.8

2x = 2

divide by 2 from both sides

/2 /2

x = 1
