To solve the equation 2x+3=11:
Start by isolating
𝑥: 2x+3=11
Subtract 3 from both sides:
2x=11−3
2x=8
Divide both sides by 2:
𝑥 = 8/ 2
x=4
Start with the equation:
3x−7=11
Add 7 to both sides to isolate the term with x:
3x−7+7=11+7
3x=18
Divide both sides by 3 to solve for x:
3𝑥/ 3 = 18/3
x=6
To find the value of 4x + 2y, we can multiply the given equation 2x + y = 5 by 2.
Multiplying both sides by 2 gives:
4x + 2y = 2(5)
4x + 2y = 10
So, the correct answer is: 10
The given differential form can be simplified as: xdy + ydx/xy = d(ln(xy))
Here's a step-by-step solution:
xdy + ydx/xy = (x/y)dy + (y/x)dx
= d(ln(y)) + d(ln(x))
= d(ln(xy))
19 x + 19 y + 17 = -19 x + 19 y – 21
38 x = -38
x = -1

To solve the equation 5x−7=3x+5:
1: Start by isolating x on one side of the equation
5x−7=3x+5
2: Subtract 3x from both sides:
5x−3x−7=5
2x−7=5
3: Add 7 to both sides:
