Solve the following system of equations: {−6x−y=2−7x−4y=−9
1 answer:
Answer:
x=-1, y=4. (-1, 4).
Step-by-step explanation:
-6x-y=2
-7x-4y=-9
----------------
y=-6x-2
-7x-4(-6x-2)=-9
-7x+24x+8=-9
17x=-9-8
17x=-17
x=-17/17
x=-1
-6(-1)-y=2
6-y=2
y=6-2=4

Answer:
x=75
Step-by-step explanation:
The triangle is isosceles, meaning that the angles V and U are congruent
Here I'll Simplify it to show the work.
You need PEMDAS
9(2*2+4÷2)
9(4+4÷2)
9(8÷2)
9(4)
9(4) = 9 × 4 = 36
The Answer is 36.
Since the values are the same on both sides the matrix value is a=1
The solution for y=2x-4: y= -8
The solution for y=3x-4: y= -12
