Question

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

Answer 1

Answer:

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

Answer 2

Answer:

x = 1

Step-by-step 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.
