Be more specific. Like what is it asking you to do ? I'm trying to help. :)
Answer:
Step-by-step explanation:
The first question:
91 = 43 + x
x = 91 - 43
x = 48
By using transposing method
Second question:
Answer:
![x>-\frac{11}{7}](https://tex.z-dn.net/?f=x%3E-%5Cfrac%7B11%7D%7B7%7D)
Step-by-step explanation:
<u>Step 1: Distribute</u>
<u />![-\frac{5}{4} (8x+4)](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B4%7D%20%288x%2B4%29%3C6-3x)
![(-\frac{5}{4} *8x)+(-\frac{5}{4} *4)](https://tex.z-dn.net/?f=%28-%5Cfrac%7B5%7D%7B4%7D%20%2A8x%29%2B%28-%5Cfrac%7B5%7D%7B4%7D%20%2A4%29%3C6-3x)
![-\frac{40x}{4}-\frac{20}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B40x%7D%7B4%7D-%5Cfrac%7B20%7D%7B4%7D%3C6-3x)
![-10x-5](https://tex.z-dn.net/?f=-10x-5%3C6-3x)
<u>Step 2: Add 10x to both sides</u>
<u />![-10x-5\mathbf{+10x}](https://tex.z-dn.net/?f=-10x-5%5Cmathbf%7B%2B10x%7D%3C6-3x%5Cmathbf%7B%2B10x%7D)
![-5](https://tex.z-dn.net/?f=-5%3C6%2B7x)
<u>Step 3: Subtract 6 from both sides</u>
<u />![-5\mathbf{-6}](https://tex.z-dn.net/?f=-5%5Cmathbf%7B-6%7D%3C6%2B7x%5Cmathbf%7B-6%7D)
![-11](https://tex.z-dn.net/?f=-11%3C7x)
<u>Step 4: Divide both sides by 7</u>
<u />![-11\mathbf{/7}](https://tex.z-dn.net/?f=-11%5Cmathbf%7B%2F7%7D%3C7x%5Cmathbf%7B%2F7%7D)
![x>-\frac{11}{7}](https://tex.z-dn.net/?f=x%3E-%5Cfrac%7B11%7D%7B7%7D)
Answer: ![x>-\frac{11}{7}](https://tex.z-dn.net/?f=x%3E-%5Cfrac%7B11%7D%7B7%7D)
Answer:
1 7/15
Step-by-step explanation:
2-1=1
then you make 2/3 and 1/5 have the same denominator -
5*3=15
?/15 ?/15
multiply 2 by 5 which is 10, so 10/15
then multiply 1 by 3 which is 3/15
subtract 3/15 from 10/15 which is 7/15
Subtract 2x from both sides
6x-4=-3
add 4 to both sides
6x=1
divide 6
x=1/6
