Answer:
y = 3/5x - 2
y = -1.5x + 3.5
y = 6x - 6
Step-by-step explanation:
<u>For equation 3x - 5y = 10:</u>
Rearraging gives;
5y = 3x - 10
Dividing throughout by 5 gives;
y = 3/5x - 2
<u>For equation 3x + 2y = 7:</u>
Rearraging gives;
2y = -3x + 7
Dividing throughout by 2 gives;
y = -3/2x + 3.5
<u>For equation 3x - 1/2y = 3:</u>
Rearraging gives;
1/2y = 3x - 3
Multiplying throughout by 2 gives;
y = 6x - 6

(26/25) x (15/28) x (8/39)
Divide top and bottom by 3 :
(26/25) x (5/28) x (8/13)
Divide top and bottom by 5 :
(26/5) x (1/28) x (8/13)
Divide top and bottom by 4 :
(26/5) x (1/7) x (2/13)
= 52 / 455 = 0.11429... (rounded)
