Question

Please help:)...........

Answer 1

Part (a)

Answer: x = 0

-----------------

Work Shown:

`3\left((x)/(7)+2\right) = 6\\\\(x)/(7)+2 = (6)/(3)\\\\(x)/(7)+2 = 2\\\\(x)/(7) = 2-2\\\\(x)/(7) = 0\\\\x = 7*0\\\\x = 0\\\\`

In step 2, I divided both sides by 3. In step 4, I subtracted 2 from both sides. In step 6, I multiplied both sides by 7.

Part (b)

Answer: x = 3

-----------------

Work Shown:

`2\left((5x)/(3)-1\right) = 8\\\\(5x)/(3)-1 = (8)/(2)\\\\(5x)/(3)-1 = 4\\\\(5x)/(3) = 4+1\\\\(5x)/(3) = 5\\\\5x = 3*5\\\\5x = 15\\\\x = (15)/(5)\\\\x = 3\\\\`

The steps are fairly similar to part (a). The steps were

• divide both sides by 2 (step 2)
• add 1 to both sides (step 4)
• multiply both sides by 5 (step 6)
• divide both sides by 5 (step 8)
