What is the value of the y-coordinate in this system of linear equations:6x+10y=-32 and 6x+9y=-27

x=3, y=-5

Step-by-step explanation:

Simultaneous equation

We will have to solve this using elimination method

6x+10y=-32 ... (1)

6x+9y=-27 ... (2)

We will start solving by eliminating x

Therefore substrate (2) from (1)

y=-5

So Let's substitute the value of y into (2)

6x+9 (-5) = -27

6x-45=-27

Add 45 to both sides

6x=18

Make x the subject of formula by dividing both sides by 6

x=3

Therefore x=3, y=-5
