Answer:
The sum is 2. ...........
Answer:
i think your question is missing something??
Step-by-step explanation:
3(4) + 6 = 7 (2(4)-3)
12 + 6 = 7 (8-3)
18 = 7 (5)
18 = 35?
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).
