Left side:
x+x+x+1+1+1+1+1+1+1+1 = 3x + 8
Right side:
x+x+x+x++1+1+1+1+1+1
Left side = Right side to solve x
3x + 8 = 4x + 6
Subtract 4x from both sides
3x + 8 - 4x = 4x + 6 - 4x
Simplify
-x + 8 = 6
Subtract 8 from both sides
-x + 8 - 8 = 6 - 8
Simplify
-x = -2
Multiply both sides by (-1)
-x * (-1) = -2 * (-1)
Simplify
x = 2
Answer
C. x = 2
Answer:
Jumper, y = 172
Shirt, x = - 105
Step-by-step explanation:
Let :
Shirt = x
Jumper = y
5x + 4y = 163 - - (1)
3x + 2y = 29 - - - (2)
Multiply (1) by 3 and (2) by 5
15x + 12y = 489 - - - (3)
15x + 10y = 145 - - - (4)
Subtract :
12y - 10y = 489 - 145
2y = 344
y = 344 / 2
y = 172
Put y = 172 in (3)
15x + 12(172) = 489
15x + 2064 = 489
15x = 489 - 2064
15x = - 1575
x = - 105
The values ;
Jumper, y = 172
Shirt, x = - 105

Step-by-step explanation:
if she starts at 4 points and her first turn she cuts 6 trees then you can add a negative 6 which is the same as subtracting that 6 when she plants 8 add those points then for her last turn add a negative 1 which is the same as subtracting 1 and she should end up with 5 points.
