To solve this problem you must apply the proccedure shown below:
1. You have the folllowing system of equations given in the problem above:
<span>
22x − y = -23 (equation 1)
11x + 12y = 1 (equation 2)
</span>
2. If you multiply the equation 2 by -2, and then sum the equation 1+equation 2, you obtain:
-25y=-25
y=1
3. Then, you must substitute y=1 into the equation 1, then you have:
x=-1
4. As you can see, when you solve it, the solutions are:
x=-1
y=1
Answer:
x = 13
Step-by-step explanation:
180-52=10x-2
130=10x
13=x
< because it used absolute value to make the |2|=2, which keeps it the same cause it’s already positive
Let s be the length of a section for plants.
Because opposite sides in a rectangle are equal we can state that 7 + 5s = 4 + 6s
Subtract 5s and 4 from both sides to get 7 - 4 = 6s - 5s which simplifies to 3 = s
The length of the wall = 7 + 5 x 3 = 22 ft
Check on opposite side: 4 + 6 x 3 = 22 ft
