You know that we have to simplify the algebra equation, so first you have to combine x and 2x. X + 2x equals to 3x. Now that we combined x and 2x which makes 3x, we have to do 7 and -8. 7 + -8 which equals to -1. Therefore, the answer to this algebra equation is 3x + -1.

X= -7+2x-8
-2x+x= -7-8
-x= -15 then multiply by -1 on both
-1(-x)= -1(-15) sides to get rid of all the x=15 negative on the x and 15

There are three consecutive even integers. If twice the first integer added to the second is 268, 244 find all three integers.

Rudik [331]

Answer:

The numbers would be 89,414 , 89,416, and 89,418

Step-by-step explanation:

In order to find this, start by setting the lowest number as x. Then we can determine that the next two even integers are x + 2 and x + 4. From this we can write the following equation.

2(x) + x + 2 = 268,244

3x + 2 = 268,244

3x = 268,242

x = 89,414

Since the first number is 89,414, we know the next two are 89,416 and 89,418.

Given that when x is reduced by 17% the answer is y, express x in terms of y.

Dima020 [189]

X - 0.17 = y

add 0.17 to both sides

x = y + 0.17
