Answer:
0
Step-by-step explanation:
1. add 2/5 to -2/5 (cancels out to 0)
2. multiply by 10 to get x on its own
3. 10*0=0
Answer:
-8
Step-by-step explanation:
Find common denominators. Note that what you do to the denominator, you must do the the numerator.
x/10 + (2 * 2)/(5 * 2) = (-2 * 2)/(5 * 2)
x/10 + 4/10 = -4/10
Simplify. Isolate the variable, x.
x/10 + 4/10 (-4/10) = -4/10 (-4/10)
x/10 = -4/10 - 4/10
x/10 = -8/10
x = -8
x = -8 is your answer.
