Answer :

To solve the problem, we need to find the value of the variable [tex]\( c \)[/tex] such that the expression [tex]\( 3 - 5c \)[/tex] is 1 less than the expression [tex]\( 1 - c \)[/tex].

Step-by-Step Solution:

1. Set up the equation based on the given condition:
The problem states that [tex]\( 3 - 5c \)[/tex] is 1 less than [tex]\( 1 - c \)[/tex]. We can write this relationship as:
[tex]\[ 3 - 5c = (1 - c) - 1 \][/tex]

2. Simplify the right-hand side of the equation:
Simplify the expression on the right-hand side:
[tex]\[ (1 - c) - 1 = 1 - c - 1 = -c \][/tex]

3. Rewrite the equation with the simplified right-hand side:
Now, the equation becomes:
[tex]\[ 3 - 5c = -c \][/tex]

4. Combine like terms:
Move all terms involving [tex]\( c \)[/tex] to one side of the equation and constants to the other side:
[tex]\[ 3 - 5c + c = 0 \][/tex]
Combine the [tex]\( c \)[/tex] terms:
[tex]\[ 3 - 4c = 0 \][/tex]

5. Isolate the variable [tex]\( c \)[/tex]:
Solve for [tex]\( c \)[/tex] by isolating it on one side of the equation:
[tex]\[ -4c = -3 \][/tex]
Divide both sides by -4:
[tex]\[ c = \frac{3}{4} \][/tex]

Therefore, the value of the variable [tex]\( c \)[/tex] that makes [tex]\( 3 - 5c \)[/tex] 1 less than [tex]\( 1 - c \)[/tex] is [tex]\( \frac{3}{4} \)[/tex].
