Answer:
x = -12.5
Step-by-step explanation:
your goal is to get x alone so
-2x - 10 = 15
(add ten to both sides)
-2x = 25
(divide -2 to both sides)
x = -12.5
remember that whatever u do to one side of the equation, you have to do to the other so they even out!
<h3><u>Solution:- </u></h3>
Let the number to be added be A
Now,
Transposing (−5x³+ 4x − 3 ) to other side-
Remember if there is a -ve sign before a bracket the signs of whole of the terms changes on opening bracket
Putting like terms together -
Therefore, 5x³+x²-5x +2 should be added to −5x³+ 4x − 3 to get x²− x − 1
-11v + 3v = -8v
-8 = 24, 24 + 8 = 32
-8v/ -8 = 32/-8
v = -4
hope this helps
Answer:
y = -2
Step-by-step explanation:
Step 1: Define
-3x - y = 56
x = -18
Step 2: Substitute and solve for <em>y</em>
-3(-18) - y = 56
54 - y = 56
-y = 2
y = -2
Answer:
