Answer
F=1+1/2
Step-by-step explanation:
(10)=-2F+13
We move all terms to the left:
(10)-(-2F+13)=0
We get rid of parentheses
2F-13+10=0
We add all the numbers together, and all the variables
2F-3=0
We move all terms containing F to the left, all other terms to the right
2F=3
F=3/2
Answer: x = 4
y = 1
Step-by-step explanation:
The given system of simultaneous equations is expressed as
- 5x + 13y = -7 - - - - - - - - - - - - 1
5x + 4y = 24 - - - - - - - - - - - - - 2
The first step is to decide on which variable to eliminate. Let us eliminate x. We would eliminate x by adding equation 1 to equation 2. It becomes
13y + 4y = - 7 + 24
17y = 17
y = 17/17
y = 1
Substituting y = 1 into equation 2, it becomes
5x + 4 × 1 = 24
5x + 4 = 24
5x = 24 - 4
5x = 20
x = 20/5
x = 4
