Answer:
x=2 and y=5
Step-by-step explanation:
Steps:
I will solve your system by substitution.
x=y−3;2x+y=9
Step: Solve x = y − 3 for x:
Step: Substitute y − 3 for x in 2x + y = 9:
2x+y=9
2(y−3)+y=9
3y−6=9(Simplify both sides of the equation)
3y−6+6=9+6(Add 6 to both sides)
3y=15
3y/3=15/3 (Divide both sides by 3)
y=5
Step: Substitute 5 for y in x = y − 3 :
x=y−3
x=5−3
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=5
Answer:
94.6
Step-by-step explanation:
100% of 44 = 44
⇒ 200% of 44 = 44 + 44 = 88
15% = 15/100 = 0.15
⇒ 15% of 44 = 0.15 x 44 = 6.6
Therefore, 215% of 44 = 88 + 6.6 = 94.6
They are closer in values.
