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)

Answer: (-17/2 , -12)
Answer:
y = -12, x = -17/2 or -8[tex]\frac{1}{2}[/tex]
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[tex]\frac{1}{2}[/tex]
