Answer:
Step-by-step explanation:
Given:
1. 1/5x - 1/3y = -1
2. -3/4x +1/3y = 12
Multiplying equation 1 by 15 and equation 2 by 12
3. 3x - 5y = -15
4. -9x + 4y = 144
and then Solving both equations simultaneously, since x = -20 as stated in the question and by confirmation,
Using equation 3 or 4 to solve for y,
3(-20) - 5y = -15
-5y = 60 - 15
y = 45/-5
= -9
y = -9
Answer:
your answer should be 2

≅ 2.4444444
Step-by-step explanation:
Add: -19 + 9 = -10
Absolute value: abs(the result of step No. 1) = abs(-10) = 10
Divide: the result of step No. 2 / 3 = 10 / 3 = 3.3333333333333 = 10/
3
Subtract: 14 - 22 = -8
Absolute value: abs(the result of step No. 4) = abs(-8) = 8
Divide: the result of step No. 5 / 9 = 8 / 9 = 0.88888888888889 = 8/

Subtract: the result of step No. 3 - the result of step No. 6 = 10/
