Please solve c=3/4y+b for b Solution The 3/4y is positive so the inverse operation is subtraction. So, subtract 3/4y from BOTH sides. c = 3/4y + b -3/4y -3/4y c - 3/4y = b b = c - 3/4y Another example, r - 5x = g, solve for x. The r is positive so the inverse is subtraction r - 5x = g -r = -r 0 -5x = g - r -5x = g - r -5x means the product of 5 and x; the inverse operation is division -5x = g - r 5 5 1x = g - r 5 5.

1. Please solve c=3/4y+b for b
Solution
The 3/4y is positive so the inverse operation is subtraction. So, subtract 3/4y from BOTH sides.
c = 3/4y + b
-3/4y -3/4y
c - 3/4y = b
b = c - 3/4y
Another example, r - 5x = g, solve for x.
The r is positive so the inverse is subtraction
r - 5x = g
-r = -r
0 -5x = g - r
-5x = g - r -5x means the product of 5 and x; the inverse operation is division
-5x = g - r
5 5
1x = g - r
5 5
