Answer:
x= 1 7/12
Step-by-step explanation:
x+1/2+x+2/3-x+3/4=2
1. We know that x+x-x=x
2. 1/2+2/3-3/4=6/12+8/12-9/12=5/12
3. x+5/12=2
4. x=2-5/12
x=1 7/12
Answer:
(2, - 4 )
Step-by-step explanation:
Given the 2 equations
x + 2y = - 6 → (1)
3x + y = 2 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the term in y
- 6x - 2y = - 4 → (3)
Add (1) and (3) term by term to eliminate y
- 5x = - 10 ( divide both sides by - 5 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
2 + 2y = - 6 ( subtract 2 from both sides )
2y = - 8 ( divide both sides by 2 )
y = - 4
Solution is (2, - 4 )
The fraction will be undefined on x=5 and x=-5
Step-by-step explanation:
The fraction is undefined on values that make the denominator of the fraction zero.
Given fraction is:
To find the values on which the denominator will be zero, we put the denominator equal to zero.
So,
The fraction will be undefined on x=5 and x=-5

Change 5/8 and 3/10 so they have the same denominator
5/8×5/5=25/40
3/10×4/4=12/40
25/40+12/40=37/40
5/8+3/10=37/40
