Answer:
1. x = 1, y = -3
2. x = 3, y = 4
Step-by-step explanation:
Here, we want to solve the sets of simultaneous equations;
a) -y = 5x-2
-3y = -5x + 14
substitute 1 into ii
3(5x-2) = -5x + 14
15x - 6 = -5x + 14
15x + 5x = 14 + 6
20x = 20
x = 20/20
x = 1
from;
-y = 5x - 2
y = -5x + 2
y = -5(1) + 2
y = -3
b) -2y = -6x + 10
2y = x + 5
Substitute ii into i
-(x + 5) = -6x + 10
-x - 5 = -6x + 10
-x + 6x = 10 + 5
5x = 15
x = 15/5
x = 3
2y = x + 5
2y = 3 + 5
2y = 8
y = 8/2
y = 4
Answer:
X=32

what does that mean?
Step-by-step explanation:
Answer:
Jillene will spend<em> $345.60</em> in 6 months.
Step-by-step explanation:
To find the answer we will turn <em>24% into a decimal</em>. 24% ÷ 100 = <em>0.24</em>. Now <em>multiply 0.24 by $240</em> and we get<em> $57.60</em>. Because we are trying to find how much Jillene will spend in 6 months, we will <em>multiply $57.60 by 6</em>, which is $345.60. Therefore, <em>$345.60 is our answer.</em>
11n-11+35=3n
11n+24=3n
11n-3n=-24
8n=-24
n=-24/8
n=-3
