1. Find the solution of the simultaneous equation: 2x − 5y = 15,

2x − 7y = 11.

(x, y) = (-10, -7)

Step-by-step explanation:

#1 Multiply the first equation by 7

#2 Then multiply the second equation by 5

1. 14x - 35y = 15

2. 10x - 35y = 55  (-

    4x           = -40

                x = -10

Then go back to equation one and replace "x" with -10

2(-10) - 5y = 15

-20 - 5y = 15

-5y = 15 + 20

-5y = 35

5y = -35

y = -7

The answer is

(x, y) = (-10, -7)

Hope this helps!

Have a nice day!

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
