I'll help you out with question #1 and follow these steps to help you with solving the rest of the problems.
1. and we know that .
We can substitute to the first equation.
Multiply both sides by 3 to get rid of the fraction.
Now you can solve for , for which the value is 15.
13/25 because I got the answer right
Answer:
7) m = 6
8) k = 15
9) a = -12
10) x = 1
11) n = 4
12) r = 11
Step-by-step explanation:
<h3><u>Solution</u> : </h3>
Solving all the questions step by step!
7) 1 = 6+m/12
- Hence, the value of m is 6.
8) 8 = 3 + k/3
- Hence, the value of k is 15.
9) -4(-8+a) = 80
- Hence, the value of a is -12.
10) 8(x-1) = 0
- Hence, the value of x is 1.
11) n/2 - 1 = 1
- Hence, the value of n is 4.
12) 1 = r-3/8
- Hence, the value of r is 11.
