What is the value of y in the solution to the system of equations? x + y = 1 2x – 3y = –30 –8 –3 3 8

Let's solve this thru elimination. Starting with x + y = 1, subtract x from both sides, obtaining y = 1 - x. This yields 2x - 3(1 - x) = - 30.

Performing the multiplication, we get 2x - 3 + 3x = -30.

Combining like terms: 5x = -27, or x = -27/5.

We already know that y = 1 - x. Thus, y = 1 - (-27/5), or y = 32/5.

The solution set is (-27/5, 32/5).

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
