Answer:
B and E
Step-by-step explanation:
(26x+2)+2=2(x+3)+1 - solution = 1/8
2x+3(x+5)=5(x-3) - NO SOLUTION
4x+3=x+12 - solution = 3
4 - (2x + 5) = {(-4x - 2) - solution = -1/2
5(x + 4) - X= 4(x + 5) - 1 - NO SOLUTION

What are the equations and anwsers?
Hello from MrBillDoesMath!
Answer:
Take you pick below! (either x 8 or x = 7.01, approx, depending how the question is interpreted)
Discussion:
Interpretation 1
If the question is
2^(x -1) = 128, then as 2^7 = 128,
x-1 = 7 so x = 8
Interpretation 2
If the question is (2^x -1) = 128, then..
2^x = 128 + 1 = 129 =>
log(2^x) = log(129) =>
xlog(2) = log(129) =>
x = log (129) / log2 = 7.01

13/3= 4.25 because.....
13-12 is 1.
SO:
When you have your problem set up, you have 4, and then a 1 left over. You turn it into a fraction.
Make 4 and 1/4, then put it as a mixed number, 4 1/4
or you can keep dividing by adding a decimal then zeroes and keep solving until you get 4.25 which is equivalent to 4 1/4
