Subtract 250-50 which equals 200 and then multiply it by 3 which is 600
Answer:
(7, 1/2)
Step-by-step explanation:
Multiply second equation by 2 and subtract.
3x - 4y = 19
- (4x - 4y = 26)
You get -x = -7
x = 7
Substitute x into any equation.
3(7) - 4y = 19
21 - 4y = 19
-4y = -2
y = 1/2
The simplified answer is 0.23
81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
