2 1/2 + x = 5 1/3
2 4/15 - z = 1 2/3
y - 6 7/8 = 2 1/16

Answers

Answer:

1- 39/6

2-36/15

3-155/16

Step-by-step explanation:

have a nice day.

Answer:

2 1/2 + x = 5 1/3

x = 5 1/3 - 2 1/2

x = 16/3 - 5/2

x = 32/6 - 15/6

x = 17/6

x = 2 5/6

2 4/15 - z = 1 2/3

-x = 1 2/3 - 2 4/15

-x = 5/3 - 34/15

-x = 25/15 - 34/15

-x = - 9/15

-x = -3/5

x = 3/5

y - 6 7/8 = 2 1/16

y = 2 1/16 + 6 7/8

y = 33/16 + 55/8

y = 33/16 + 110/16

y = 143/16

y = 8 15/16

For the following equations, draw a picture of the tiles on an Equation Mat. Then use “legal” moves to simplify and solve for the variable.


a. -2+x = -x+2


b. 2+3x = x+7

Answers

I can solve these for you

a:
-2+x=-x+2
+2 +2
x=-x+4
+x +x
2x=4
— —
2 2
x=2

so the solution to a is x=2


b:

-2 -2
3x=x+5
-x -x
2x=5
