Answer:

3. x-2

Step-by-step explanation:

Let's start with 1. we know that 2-x is the same as -2+x and since addition can be written as -2+x or x+(-2) and equal the same thing, we know that x-2 is the one that is not equivalent.

Solve the equation for t. <br><br>1/2 t +8 = 5/2 t - 10​
Elden [556K]

Simplif 1/2t to t/2

t/2 + 8 = 5/2t - 10

Simplify 5/2t to 5t/2

t/2 + 8 = 5t/2 - 10

Multiply both sides by 2

t + 16 = 5t - 20

Subtract t from both sides

16 = 5t - 20 - t

Simplify 5t - 20 - t to 4t - 20

16 = 4t - 20

Add 20 to both sides

16 + 20 = 4t

Simplify 16 + 20 to 36

36 = 4t

Divide both sides by 4

36/4 = t

Simplify 36/4 to 9

9 = t

Switch sides

<u>t = 9</u>
