Distribute the 5(2-y).
You get:
10 - 5y + y =  - 6
Add like terms.
10 - 4y =  - 6
Get the variable by itself. In this case, subtract ten from both sides.
- 4y =  - 16
To get the variable alone, divide by -4.
You get:
y = 4
Hope this helped!

Hello!

<u><em>Answer:</em></u>

<u><em>y=4</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, expand form.

5(2-y)=10-5y

10-5y+y=-6

Then you add by the similar elements.

-5y+y=-4y

10-4y=-6

Next, you subtract by 10 from both sides of an equation.

10-4y-10=-6-10

Simplify.

-4y=-16

You can also divide by -4 from both sides of an equation.

\frac{-4y}{-4}= \frac{-16}{-4}

And finally, you simplify and solve. Then you divide by the numbers.

16/4=4

Final answer: → y=4

Hope this helps!

Thanks!

Have a great day!

Fynjy0 [20]

Answer:

Step-by-step explanation:

1.  Interchange x and y.  We get:  x = y^2 - 5

2. Solve for y:  y^2 = x + 5, so that y = ±√(x + 5)

Simplify the expression and then substitute the given number for the variable. For expression 8a2+6b+9a2+9b2+3b, find the value
Harlamova29_29 [7]

Answer: 68

Step-by-step explanation:

Simplifying the expression:

= 8a² + 6b + 9a² + 9b² + 3b

Collect like terms

= 8a² + 9a² + 6b + 3b + 9b²

= 17a² + 9b + 9b²

We then substitute a=2,b=−1.

= 17a² + 9b + 9b²

= 17(2)² + 9(-1) + 9(-1)²

= 68 -9 + 9

= 68

The width of a triangle is six more than twice the height. The area of the triangle is 88in2. Find the height and base of the tr
malfutka [58]

For this case we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

Where:

b: It is the base of the triangle

h: It is the height of the triangle

According to the statement data we have:

b = 6 + 2h

Substituting we have:

88 = \frac {(6 + 2h) * h} {2}\\176 = 6h + 2h ^ 2\\2h ^ 2 + 6h-176 = 0

We divide between 2 on both sides:

h ^ 2 + 3h-88 = 0

We factor by looking for two numbers that, when multiplied, are obtained -88 and when added together, +3 is obtained.

These numbers are +11 and -8.

(h + 11) (h-8) = 0

We have two roots:

h = -11\\h = 8

We choose the positive value.

Thus, the base of the triangle is:b = 6 + 2 (8) = 22

Answer:

The base of the triangle is 22 units.
