Answer: 207 over 16 or in decimal form 12.9375
Step by step explanation:
Add 15 and 3 to get 18
9+ 7x18 over 32
Multiply the 7 and 18 to get 126
9+ 126 over 32
Reduce the fraction 126 over 32 to get the lowest terms by extracting and cancelling out the 2
9+ 63 over16
Convert 9 into the fraction 144 over 16
144over16 +63over16
Both of the fractions have the same denominator, therefore you should add them by using their numerators.
144+16over16
Add 144 and 63 to get the final number.
207over16

Answer:
Step-by-step explanation:
3x+4=−y
3x+4+y=−y+y(Add y to both sides)
3x+y+4=0
3x+y+4+−3x=0+−3x(Add -3x to both sides)
y+4=−3x
y+4+−4=−3x+−4(Add -4 to both sides)
y=−3x−4
Step: Substitute−3x−4foryin2x+y=0:
2x+y=0
2x+−3x−4=0
−x−4=0(Simplify both sides of the equation)
−x−4+4=0+4(Add 4 to both sides)
−x=4
−x
−1
=
4
−1
(Divide both sides by -1)
x=−4
Step: Substitute−4forxiny=−3x−4:
y=−3x−4
y=(−3)(−4)−4
y=8(Simplify both sides of the equation)
Answer:
x=−4 and y=8
