Answer:
Step-by-step explanation:
y=9x-1
8x-4y=92
substitute y=9x-1
8x-4(9x-1)=92
8x-36x+4=92
-28x+4=92
-28x=92-4=88
x=88/-28=22/-7 = -3.14
y = 9(-3.14) -1 = -28.26-1 = -29.26
The answer would be 4.12 because the other one is a negative

======================================
Work Shown:
Draw out a rectangle that is 32 units wide horizontally and 8 units tall vertically.
Then draw out another rectangle that is 4 meters wide horizontally and x meters tall vertically.
The horizontal and vertical sides pair up to form these fractions: 32/4 and 8/x
Set the fractions equal to one another. Solve for x
32/4 = 8/x
32x = 8*4 ... cross multiply
32x = 32
x = 32/32 ... divide both sides by 32
x = 1
-----------------------
Somewhere else on your paper, draw the same 32 by 8 rectangle to make 32 the horizontal component
Next to this rectangle, draw a rectangle that has x as the horizontal part and 4 as the vertical. Note the swap here.
We now have this equation to solve for
32/x = 8/4
once again, note the swap
Let's solve for x
32/x = 8/4
32*4 = 8*x
128 = 8x
8x = 128
x = 128/8
x = 16
10 1/2 that is the your right I am a ten year old boy I know this wow you cant do it I believe in you you can do it
