To solve the equation 3.2 - x = -5.1, we need to isolate the variable x.
First, we will subtract 3.2 from both sides of the equation:
3.2 - x - 3.2 = -5.1 - 3.2-x = -8.3
Next, we need to multiply both sides by -1 to solve for x:
x = 8.3
The value of x is 8.3.
To solve the equation y + (3 3/14) = 1 4/21, we need to subtract (3 3/14) from both sides of the equation:
y = 1 4/21 - 3 3/14
First, convert the mixed numbers to improper fractions:(211+4)/21 = 25/21(213+3)/14 = 66/14
Now, subtract:y = 25/21 - 66/14y = (252 - 663)/(21*2)y = (50 - 198)/42y = -148/42y = -74/21
The value of y is -74/21.
To solve the equation 3.2 - x = -5.1, we need to isolate the variable x.
First, we will subtract 3.2 from both sides of the equation:
3.2 - x - 3.2 = -5.1 - 3.2
-x = -8.3
Next, we need to multiply both sides by -1 to solve for x:
x = 8.3
The value of x is 8.3.
To solve the equation y + (3 3/14) = 1 4/21, we need to subtract (3 3/14) from both sides of the equation:
y = 1 4/21 - 3 3/14
First, convert the mixed numbers to improper fractions:
(211+4)/21 = 25/21
(213+3)/14 = 66/14
Now, subtract:

y = (252 - 663)/(21*2)
y = (50 - 198)/42
y = -148/42
y = -74/21
The value of y is -74/21.
