Answer:

<h2>0.67</h2>

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...

Best regards!!

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

Check whether p=-2 is a solution of the equation 7p-5=20 or not ...​
Lana71 [14]

Answer:

not a solution

Step-by-step explanation:

Substitute p = - 2 into the left side of the equation and if equal to the right side then it is a solution.

7(- 2) - 5 = - 14 - 5 = - 19 ≠ 20

Then p = - 2 is not a solution of the equation
