163,000 is that rounded to the nearest hundred.
Answer:
The actual answer is 9.25
Step-by-step explanation:
The mistake is in Step 4, as <u>4 × 2 = 8</u>, not 6
The correct answer is (1,2)
Steps:
Multiply the second equation by 6 in order to eliminate the x variable.
6x-7y= -8
6(-x-4y= -9)
6x-7y= -8
-6x-24y=-54
Add the equations together and solve for y
-31y= -62
Y=2
Substitute y=2 in the original equation
-x-4(2)= -9
-x-8= -9
-x= -1
X=1
Answer: (1,2)
