Answer:
Step-by-step explanation:
y=x+7.........(1)
y=3x+5.......(2)
Equating the two equations
3x +5 = x + 7
3x -x = 7 - 5
2x = 2
x = 2/2
x = 1
Putting x = 1 in (1)
y = x + 7
y = 1 + 7
y = 8
Use simultaneous equations
a + c =6 (1)
45a + 15c = 150 (2)
from (1)
c = 6-a (3)
sub 3 into (2)
so the answer is 45a + 15(6-a) = 150, so is B
