Answer:
1= -4a+7b
2=(7x-5)/3
Step-by-step explanation:
1,
a+3b-(5a-4b)
expand bracket 1st according to BIDMAS
a+3b-5a+4b
collect like terms
a-5a+3b+4b
ans=-4a+7b
2,
X/3+2x-5/3
solve for the 1st two
X/3 +2x
LCM =3 so,
(x+6x)/3=7x/3
use this and solve the last part
(7x/3)-(5/3)
LCM=3
ans=(7x-5)/3

The value of the x is 3.22 if the eˣ = 25 after taking the log both side and lne is 1.
<h3>What is a logarithm? </h3>
It is another way to represent the power of numbers, and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
We have:
Taking ln both side:
xlne = 3.218
x = 3.218 (lne = 1)
or
x = 3.22
Thus, the value of the x is 3.22 if the eˣ = 25 after taking the log both side and lne is 1.
