Answer:
(1) x=
−1
/2
y+
5
/2
(2)
x=
−1
/2
y−2
Step-by-step explanation:
<u>(1)</u> 2x+y=5
Step 1: Add -y to both sides.
2x+y+−y=5+−y
2x=−y+5
Step 2: Divide both sides by 2.
2x
/2
=
(−y+5)/2
x=
−1
/2
y+
5
/2
<u>(2) </u>Step 1: Flip the equation.
−2x−4=y
Step 2: Add 4 to both sides.
−2x−4+4=y+4
−2x=y+4
Step 3: Divide both sides by -2.
−2x
/−2
=
(y+4)
/−2
x=
−1
/2
y−2
Answer:
x = 10; x = 0
Step-by-step explanation:
x < 29 means x is less than 29. Any number less then 29 is a solution.
For example, pick x = 10. Since 10 < 29, x = 10 is a solution. How do we know x = 10 is a solution?
We start with x < 29.
Now replace x with 10.
10 < 29
Since 10 < 29 is a true statement, then x = 10 is a solution.
Now pick another number less than 29. For example, oick 0.
x = 0 is a solution.
Proof:
x < 29
Replace x with 0:
0 < 29
Since 0 < 29 is a true statement, then x = 0 is a solution.
You can give more solutions just by picking any numbers that are less than 29, such as 1, 2, 3, 15, 28, 23, -5, -18, etc.
Answer: x = 10; x = 0
Answer:
9 : 3
Step-by-step explanation:
To get from 21 to 3 we divided 21 by 7, therefore we have to do the same to the other side and so we get...
63 / 7 = 9
Therefore 63 : 21 = 9 : 3
