Answer:
x = z - m
Step-by-step explanation:
<u>Solving for x with steps:</u>
- z=m+x
- x + m = z
- x + m - m = z - m
- x = z - m
Answer:
The solution is x = -2, y = -3
Step-by-step explanation:
Let's start with the equation 3x + y = -9
Substitute the y for 5x+7 seen in the second equation
Now you have 3x + (5x+7) = -9
Lets solve:
Let's add the x's
Now we have 8x + 7 = -9
Substracy seven from each side
Now we have 8x = -16
Now let's divide 8 on each side
Now we have x = -2
Now lets plug in -2 to the second equation
The second equation is y = 5x+7
When we plug in -2 we get y=5(-2)+7
We multiply
We now have y = -10+7
Add
y = -3
The solution is x = -2, y = -3
7/10 you just get the decimal form of the numbers and find a simple decimal between them, which was 7, and put it over 10 so you get 7/10
Answer
<h2>
4</h2>
Step-by-step explanation:
Given,
r = 10
Let's create an equation,
plugging the value of r
Multiply the numbers
Move 5s to L.H.S and change its sign
Similarly, Move 30 to R.H.S and change its sign.
Calculate
The difference sign ( - ) should be cancelled on both sides
Divide both sides of the equation by 5
Calculate
The value of s is 4.
Hope this helps..
Best regards!!
