Question

Solve the equation.

2(x + 5) = 3x + 1



x = _____

Answer 1

x=9

Explanation:

2(x+5) = 3x =1

2x + 10 = 3x + 1

10 = x + 1

9 = x

Step 1: Start out by using distributing property. You distribute the 2 to the x and the five, making 2x + 10.

Step 2: You put the variables on one side, keeping them positive. So you do the opposite of +2x, which is -2x. So you subtract 2x from 3x leaving you with 1x or x.

Step 3: You take the numbers and put them on one side, meaning you have to move the +1. TO do that, you do the opposite and take it away from the 10 leaving you with 9 = x

Answer 2

x=9

Explanation:

1. expand brackets first

2(x + 5) = 3x + 1

2x +10=3x +1

2. subrtract2 x from both sides

2x +10=3x +1

10= x +1

3. subtract 1 from both sides

10= x + 1

9+x
