Answer:
y = 8x + 72
Step-by-step explanation:
420=7/6x
The 6, who was under / now goes across the equal sign with * value.
420*6 =7x
2520 = 7x
Now the 7, who is under * value, goes across the equal sign with / value, so
2520/7 = x
x= 360.
420-360 = 60
It earned $60 of interest.
Answer:
x = 3b/2 + 3y/2
Step-by-step explanation:
Goal: Find x
To do that we must isolate x on one side of the equation.
2/3x - y = b
2/3x - y + y = b + y
2/3x = b + y
2/3x ÷ 2/3 = b + y ÷ 2/3
(When we divide fractions we multiply by its reciprocol.)
x = 3b/2 + 3y/2
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
