Answer:
Step-by-step explanation:
Multiplying x+6y=-3 with 2 so its equal to first eqn,
Eliminating,
2x + 3y = 3 (1)
2x +12y = -6 (2) (because subtracting)
------------------
-9y =9
∴y=-1
eq. y in 1
2x -3=3
2x=3+3
x=6/2
=3

Answer:
$10
Step-by-step explanation:
Since 6 cost four dollars 3 would cost 2 dollars multiply 3 to get 15 bananas and 2 to get $10
C. Plumber A and Plumber B will both charge $135 if they each work 2.5 h.
Answer:
6x + y = 1
y = 1 - 6x
7x + 2(1 - 6x) = -3 substitute 1 - 6x in for y
7x + 2 - 12x = -3 combine like terms
2 - 5x = -3 subtract 2 from both sides
-5x = -5 divide by -5
x = 1
