9a-2b=-8.....1
-7a+3b=12.....2
So,
1 equation into 3 and 2 equation into 2.
Then,
18a-6b=-24
-14a+6b=24.
4a=0 a=0 .
Substitute a value in 2 equation.
b=4.
Hope it helped
Answer:
(-1,-2)
Step-by-step explanation:
There is a solution where the two expressions intersect. We can plug in what we know in the first equation in the second.
x= -1
y=3x+1
y= 3(-1)+1
y= -3+1
y= -2
Plugging y value in the equation to find x:
-2=3x+1
-3=3x
x= -1
Therefore, the point is (-1,-2)
