Answer:
4y + (y − 1) = 29
(2y + 3) − 4 = 9
4y − y + 1 = 13
Step-by-step explanation:
We will have to check each equation for the given values of y.
So,
1. (2y + 3) − 4 = 9
For y=4
[2(4)+3]-4=9
(8+3)-4=9
11-4=9
7=9
Not true for 4
For y=5
[2(5)+3]-4=9
(10+3)-4=9
13-4=9
9=9
True for 5
2. 4y − y + 1 = 13
For y=4
4(4)-4+1=13
16-4+1=13
13=13
True for 4
3. 4y + (y − 1) = 29
As we have already used 4 and 5 we will check for 6 and onwards
For y=6
6(4)+(6-1)=29
24+5=29
29=29
So the equations in decresing order of y that make them true are:
4y + (y − 1) = 29
(2y + 3) − 4 = 9
4y − y + 1 = 13 ..

Answer:
x = 21
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
Combine like terms. (x + 3x) and (-4 + 100)
x - 4 + 3x + 100 = 180
Subtract 96 on both sides.
4x + 96 = 180
-96 -96
Divide 4 on both sides.
4x = 84
--- -----
4 4
And you get a solution of 21.
x = 21
<u>Check:</u>
Substitute 21 into x.
Add/Subtract from left to right.
21 - 4 + 3(21) + 100 = 180
17 + 63 + 100 = 180
80 + 100 = 180
180 = 180
