Question 619640
I assume each side is above so basically add each side together and that will equal 218 in then solve for x:

2x + x + 6x-7 = 218

rearrange so all X's on one side and numbers on the other. If you move one from one side of the = to the other side then change the sign so:

2x + x + 6x = 218 + 7
9x = 225

so divide both sides by 9 to find x:

9x/9 = 225/9
x = 25

so x = 25

Now we can find the value of each side.
First one was 2x so 2 times 25 = 50

The second one was x so is 25

The third was 6x-7 = 6(25) - 7
 = 143

To check add the three sides together to see if they equal 218 so:

50 + 25 + 143 = 218!!!
