2x +8=2(x + 4)
mutiply the bracket by 2
(2)(x)= 2x
(2)(4)= 8
2x+8= 2x+8
move 2x to the left side
sign changes from +2x to -2x
2x-2x+8= 2x-2x+8
0+8= 0+8
8= 8
Answer:
All real numbers
Answer:
Step-by-step explanation:
s>7
So, all values greater than 7 are included in the number line.
Step-by-step explanation:
We need to use number line to show numbers in the solution set of the inequality 2s+ 36 greater than 50
Solving and finding value of s:
2s+36>50
Adding -36 on both sides
2s+36-36>50-36
2s>14
Divide both sides by 2
s>7
So, all values greater than 7 are included in the number line.
The number line is shown in figure attached below

e+v=26
total 10 points
2e+5v=100
so we gots
e+v=26 and
2e+5v=100
elimination
multiply first equation by -2 and add to 2nd equation
-2e-2v=-52
<u>2e+5v=100 +</u>
0e+3v=48
3v=48
divide both sides by 3
v=16
sub back
e+v=26
e+16=26
minus 16 both sides
e=10
