Question

Hi need help with three math problems

Solve the formula for the given variable
54. 5x-2y=22 for y
53. 4x+3y=12 for y
51. 9x+3y=6 for y

Answer 1

54. 5x - 2y = 22 for y
first subtract 5x from each side
-2y = 22 - 5x
then divide everything by -2 to get y by itself
y = (22 - 5x)/-2
or
y = -11 + 5/2x

53. 4x + 3y = 12 for y
subtract 4x from each side
3y = 12 - 4x
divide the equation by 3
y = (12 - 4x)/3
or
y = 4 - 4/3x

51. 9x + 3y = 6 for y
subtract 9x from each side
3y = 6 - 9x
divide by 3
y = (6 - 9x)/3
or
y = 2 - 3x
