Answer:
First image: (6, -1)
2nd image: y = 63
Explanation:
1)
2x + y = 11
1/2x - 5y = 8
y = -2x + 11
1/2x - 5(-2x + 11) = 8
1/2x + 10x - 55 = 8
10.5x - 55 = 8
10.5x = 63
x = 6
2x + y = 11
2(6) + y = 11
12 + y = 11
y = -1
(x , y) = (6, -1)
2)
1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5
2y - 1.2 = 1.8y + 10.8 + 0.6
0.2y - 1.2 = 11.4
0.2y = 12.6
y = 63
Answer:
false
Step-by-step explanation:
3x+4y=24 multiplied by 2 equals: 6x+8y=48
if you subtract 6x+8y=24 from 6x+8y=48, you get 0=24, which is not true. Therefore the statement is false.
Answer:
y-3=-0/2(x+2)
Step-by-step explanation:

Set up your equation:
174.99=24.99+12.50x
subtract 24.99 from boh sides of the equation to get:
150=12.50x
then divide both sides by 12.50 to get:
12=x or x=12
