Question

What is the solution to this equation 3x -x + 8 + 5x -2 = 10

Answer 1

3x -x + 8 + 5x -2 = 10

First, combine like terms

3x - x + 5x = 7x

8 - 2 = 6

7x + 6 = 10

Note the equal sign. What you do to one side you do to the other. Do the opposite of PEMDAS. First subtract 6 from both sides

7x + 6 (-6) = 10 (-6)

7x = 10 - 6

7x = 4

Next, isolate the x by dividing 7 from both sides

7x/7 = 4/7

x = 4/7

x = 4/7, or (B) is your answer

hope this helps

Answer 2

Answer:

Correct option is:

B. x=4/7

Step-by-step explanation:

We have to solve the equation:

3x-x+8+5x-2= 10

On combining the like terms, we get

3x-x+5x+8-2=10

x(3-1+5)+6=10

7x+6=10

On subtracting both sides by 6, we get

7x=4

On dividing both sides by 7, we get

x=4/7

Hence, Correct option is:

B. x=4/7
