8b + 23 = -4.2
You need to solve for B.
8b= -4.2 -23
What would you have to do next in order to get B by itself?
23 + -23 + 8b = 4.2 + -23
Combine like terms: 23 + -23 = 0
0 + 8b = 4.2 + -23
8b = 4.2 + -23
Combine like terms: 4.2 + -23 = -18.8
8b = -18.8
Divide each side by '8'.
b = -2.35
Simplifying
b = -2.35
To find the value of b in the equation 8b + 23 = -4.2, we'll need to isolate the variable b. Here's how you can solve it:
Step 1: Subtract 23 from both sides of the equation to move the constant term to the other side:
8b + 23 - 23 = -4.2 - 23.
Simplifying this gives:
8b = -27.2.
Step 2: Divide both sides of the equation by 8 to isolate the variable b:
8b / 8 = -27.2 / 8.
Simplifying this gives:
b = -3.4.
Therefore, the value of b in the equation 8b + 23 = -4.2 is -3.4.
