galina1969 [7]

Simplify algebraic expression y+3y-2
Tcecarenko [31]

Answer:

the answer is 4y-2

Step-by-step explanation:

To simplify any algebraic expression you need to add liketerms.

In this equation, the liketerms are y and 3y.

3y+y= 4y

We are left with 4y-2; we cant go any further, because 4y and -2 are not liketerms.

6x+2=-8+3x+25 whats the answer to x?
Nitella [24]

Answer:

x = 5

Step-by-step explanation:

To find the value of x make sure to get it on one side

First subtract 3x from each side. This makes the equation now

3x + 2 = -8 + 25

Now see what 25 subtract by 8 is (17)

3x + 2 = 17

Next subtract 2 from both sides

3x = 15

Lastly, divide 15 by 3, making x equal 5

x = 5
