Solve the equation for y
3x+1/5y=7


Sagot :

Answer:

x = 35 - y / 15

Step-by-step explanation:

3x + 1/5y = 7

3x + 1/5y - 1/5y = 7 - 1/5y

3x = 7 - 1/5y

3x/3 = 7/3 - 1/5y / 3

x = 35 - y / 15

Answer

y=35-15x

Step by step

Subtract 3x from both sides

1/5y=7-3x

Divide by 1/5 (times by the reciprocal wich is 5)

y=35-15x
