2 times the sum of a number and 8 is equal to the difference of 10 and that number find the number

1 answer:

7 0

The equation would look like this
2 (x + 8) = 10 - x
First you distribute: 2x +16 = 10 - x
Next you isolate the variable by adding x to each side and subtracting 16 from each side: 3x = 10 - 16
Simplify: 3x = -6
Divide both sides by 3: x = -2

How many solutions does the equation 6y - 3y -7 = -2 +3 have?

kenny6666 [7]

Answer:

6y - 3y - 7 = -2 +3

Simplify both sides:

3y -7 = 1

Add 7 to both sides:

3y = 8

Divide both sides by 3:

y = 8/3 = 2 2/3

There is only one solution.
