3x + 4y = 5
2x - 5y = 8
To answer this question, we need to put both of these equations into Slope-Intercept form, or in other words, solve for y.
3x + 4y = 5 Subtract 3x from both sides
4y = -3x + 5 Divide both sides by 4
y =
+ 
2x - 5y = 8 Subtract 2x from both sides
-5y = -2x + 8 Divide both sides by -5
y =
- 
When you look at the two equations, you can see that their slopes are completely different, so they aren't parallel, or inconsistent. Since is not the same as<span> , they aren't the same line, or dependent. So, the only option left is that they are consistent and independent.</span>

Answer:
The solution of the equation is ⇒ 3rd answer
Step-by-step explanation:
* Lets explain how to solve this problem
- The function f(x) = e^x is called the (natural) exponential function
- The natural logarithm (㏑), or logarithm to base e, is the inverse
function to the natural exponential function
∵ is an exponential function
∴ We can solve it by using the inverse of e (㏑)
- Remember:
#
#
- Insert ln in both sides
∴
∵
∴ 2x + 5 = ㏑(4)
- Subtract 5 from both sides
∴ 2x = ㏑(4) - 5
- Divide both sides by 2 to find x
∴
* The solution of the equation is
