Question

10(1 – 2y) = -5(2Y - 1)

Answer 1

Answer:

y =1/2

Step-by-step explanation:

solve for ; y

10(1 – 2y) = -5(2Y - 1)

-10(2y-1) +5(2Y - 1) =0

(2y-1)(-10+5) = 0

-5(2y-1) =0

2y-1=0

y = 1/2

Answer 2

Answer:

y = 1/2

Step-by-step explanation:

1) 10(1 - 2y) = -5(2y - 1)

• Multiply 10 into the parentheses, then multiply -5 into the parentheses.

2) 10 - 20y = -10y + 5

• Remember, double negatives when multiplying make positive numbers
• Next, switch -10y with 5 so you'll have like terms on each side.

3) 10y - 20y = -10 + 5

• When you switch terms, you change the signs of them to either negative/positive.
• Now, subtract 10y - 20y & add -10 & 5 together.

4) -10y = -5

• Divide -10 into -5.

5) y = -5/-10

• What is present above is not the correct answer. You must simplify the fraction, & make the fraction a positive one.

6) y = 1/2

Now you have your answer. 10(1 - 2y) = -5(2y -1) is 1/2 or 0.5

Here's how to check your answer.

10(1 - 2(1/2)) = -5(2(1/2) - 1)

10(1 - 1) = -5(1 - 1)

• 2 times 1/2 equals 2/2, which would then be revised to 1.

10(0) = -5(0)

0=0
