Answer:
x= -10/3
y= -8/9
Step-by-step explanation:
2x+1=3(y−1);6(2y−1)=5x
Rewrite equations:
2x+1=3y−3;12y−6=5x
Step: Solve2x+1=3y−3for x:
2x+1=3y−3
2x+1+−1=3y−3+−1(Add -1 to both sides)
2x=3y−4
2x2=3y−42(Divide both sides by 2)
x=32y−2
Step: Substitute32y−2forxin12y−6=5x:
12y−6=5x
12y−6=5(32y−2)
12y−6=152y−10(Simplify both sides of the equation)
12y−6+−152y=152y−10+−152y(Add (-15)/2y to both sides)
92y−6=−10
92y−6+6=−10+6(Add 6 to both sides)
92y=−4
92y92=−492(Divide both sides by 9/2)
y=−89
Step: Substitute−89foryinx=32y−2:
x=32y−2
x=32(−89)−2
x=−103(Simplify both sides of the equation)
Answer:
the hot air balloon is hotter than me
Step-by-step explanation:
Answer:
F = 2
Step-by-step explanation: If you want to know which one is a solution, you have to substitute the numbers in for F.
F = 7:
3 > f
3 > 7
This is false because 3 is NOT greater than 7, it is less than 7.
F = 9:
3 > f
3 > 9
This is false because 3 is NOT greater than 9, it is less than 9.
F = 2:
3 > f
3 > 2
This is TRUE because 3 IS greater than 2.
Hope this help you!!! :)
