Answer 1

0.67

Explanation:

`5(y - 3.8) = 4.7(y - 4)`

Distribute 5 through the parentheses

`5y - 19 = 4.7(y - 4)`

Distribute 4.7 through the parentheses

`5y - 19 = 4.7y - 18.8`

Move ' 4.7 y ' to L.H.S and change it's sign

`5y - 4.7y - 19 = - 18.8`

Move constant to R.H.S and change it's sign

`5y - 4.7y = - 18.8 + 19`

Collect like terms

`0.3y = - 18.8 + 19`

Calculate

`0.3y = 0.2`

Divide both sides of the equation by 0.3

`(0.3y)/(0.3) = (0.2)/(0.3)`

Calculate

`y = 0.67`

Hope this helps...

Best regards!!

Answer 2

`y = 0.67` (To 2 dps)

y = 0.7 (To 1 dps)

y = 1 (To nearest whole no.)

Explanation:

`5(y-3.8) = 4.7 (y-4)`

Distribute the terms

`5y - 19 = 4.7y-18.8`

Combining like terms

`5y - 4.7y = -18.8+19`

Adding and subtracting

`0.3y = 0.2`

Dividing both sides by 0.3

`y = 0.2/0.3`

`y = 0.67`
