Let's solve your equation step-by-step.
2(x+4)=−5x+1
Step 1: Simplify both sides of the equation.
2(x+4)=−5x+1
(2)(x)+(2)(4)=−5x+1(Distribute)
2x+8=−5x+1
Step 2: Add 5x to both sides.
2x+8+5x=−5x+1+5x
7x+8=1
Step 3: Subtract 8 from both sides.
7x+8−8=1−8
7x=−7
Step 4: Divide both sides by 7.
7x
7
=
−7

x=−1
Answer:
x=−1
The median is wrong because the median is the middle number
Answer and Step-by-step explanation:
1) - 6.5 r = - 58.5
- r = - 58.5/6.5
- r = - 9
<h2>r = 9 </h2>
2) c - 5.5 = 2.3
c = 2.3 + 5.5
<h2>c = 7.8</h2>
3) 56 = - 5.6s
56/5.6 = - s
10 = - s
- 10 = s
<h2>s = - 10</h2>
4) d/4 = 4.7
d = 4.7 / 1/4
d = 4.7 * 4
<h2>d = 18.8</h2>
5) - 9 = 6.9 + x
- 9 - 6.9 = x
- 15.9 = x
<h2>x = - 15.9</h2>
6) 23.5 = 4.7z
23.5/4.7 = z
5 = z
<h2>z = 5</h2>
7) - 2.7 = v + 4.9
- 2.7 - 4.9 = v
- 7.6 = v
<h2>v = - 7.6</h2>
8) 2.6 = k/3
k/3 = 2.6
k = 2.6 / 1/3
k = 2.6 * 3
<h2>k = 7.8</h2>
9) - 5.6f = 44.8
- f = 44.8/5.6
- f = 8
<h2>f = - 8</h2><h2 />
hope it helps, my friend
