Answer 1

Answer:

0.67

Step-by-step 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

$\frac{0.3y}{0.3} = \frac{0.2}{0.3}$

Calculate

$y = 0.67$

Hope this helps...

Answer 2

Answer:

$y = 0.67$   (To 2 dps)

y = 0.7 (To 1 dps)

y = 1 (To nearest whole no.)

Step-by-step 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

$y = 0.2/0.3$

$y = 0.67$
