X is 18
You need to algebraically move things around by adding/dividing on both sides (work shown in the picture).
You need to algebraically move things around by adding/dividing on both sides (work shown in the picture).
Solve Equation:
3 ( 110 - 7x ) = x - 66
Simplify both sides:
3 ( 110 - 7x ) = x - 66
( 3 ) ( 110 ) + ( 3 ) ( - 7x ) = x + - 66
Distribute:
330 + -21x = x + - 66
- 21x + 330 = x - 66
Step 2: Subtract x both sides:
- 21x + 330 - x = x - 66 - x
- 22x + 330 = -66
Step3: Subtract 330 both sides:
- 22x + 330 - 330 = - 66 - 330
- 22x = - 396
Step 4: divide both sides by - 22:
- 22x / - 22 = - 396 / - 22
x = 18
Answer: 3 ( 110 - 7x ) = x - 66 =====> x = 18
Hope that helps!!!! : )

Given the points H(6,7) and I(-7,-6).
If point G lies of the way along line segment HI.
Therefore, we can say that the point G divides the line segment HI in the ratio 1:1.
So, by using the cross section formula we can determine the coordinates of point G.
For the given points say and
divided is in the ratio
, the coordinates are
Coordinates G =
= (-0.5 , 0.5)
Hence, the coordinates of G are (-0.5 , 0.5).
So, Santiago argues that point G is located at the origin. The point G is located at (-0.5, 0.5). Therefore, he is not correct.
