Step-by-step explanation:
To solve for x, we set up our equation like this:
7x - 7 = 4x + 14
Next, we subtract 4x from the right side to cancel it out and then subtract 4x from the left side.
7x (-4x) - 7 = 4x (-4x) + 14
3x - 7 = 14
Then, we add 7 on both sides (to cancel the -7 out and place it on the right)
3x - 7 (+7) = 14 + 7
3x = 21
Finally, we divide both sides by 3 to isolate our variable, x.
3x ÷ 3 = x
21 ÷ 3 = 7
Our final answer: x = 7
Answer:
solution set={35/3}
<u>Step-by-step explanation:</u>
--3(x+5)=50
- opening brackets to simplify
3x+15=50
- subtracting 15 on both sides to find the value of x
3x+15-15=50-15
3x=35
- dividing 3 on both sides to find the value of x
3x/3=35/3
x=35/3=11.66
solution set={35/3}

Answer:
6/2
Step-by-step explanation:
Answer:
(x + 2) (3x + 1)
Step-by-step explanation:
3x² + 7x + 2
3x² + 6x + x + 2
3x(x + 2) + 1(x + 2)
<em><u>(x + 2) (3x + 1)</u></em>
