2x+5y=-55 y=3x+6 what is the solution

Hey there!!

We have 2 equations.

... 2x+5y=-55 and y=3x+6

Substitution method:

... 2x+5(3x+6)=-55

... 2x+15x+30=-55

... 17x+30=-55

Subtracting 30 on both sides:

... 17x=-55-30

... 17x=-85

Dividing by 17 on both sides:

... x=-85/17

... x = -5

The value of x is -5.

We have:

... 2x+5y=-55

... 2(-5)+5y=-55

... -10+5y=-55

Adding by 10 on both sides:

... 5y=-55+10

... 5y=-45

Dividing by 5 on both sides:

... y=-9

Hence, the value of 'x' is -5 and the value of 'y' is -9.

Hope my answer helps!
