Question

-7 + y = -19 -2x + 3y = -19

Answer 1

Answer:

y = -12, x = -17/2 or -8$\frac{1}{2}$

Step-by-step explanation:

-7 + y = -19 . . . . . . .. . eq1

-2x + 3y = -19  . . . . . . .eq 2

solve for y in eq 1

that is y = -19 + 7

          y = -12

substitute y into eq 2.

-2x + 3(-12) = -19

-2x - 36 = -19

-2x = -19 + 36

-2x = 17

x = -17/2 or -8$\frac{1}{2}$

Answer 2

If you want to solve the system of equations it will be:

Step 1: solve the equation for y

y= -19+7 → y= -12

Step 2: substitute y into the equation

-2x+3x(-12)=-19

Step 3: solve the equation for x

x= -17/2

Step 5: the possible solution is the order pair (x,y)

Answer: (-17/2 , -12)
