11.70 + 2*3.90 + d = 21.08 + 2.00
how do I find out d?
Combine like terms.
11.70 + 2*3.90 + d = 21.08 + 2.00
11.70 + 7.8 + d = 23.08
19.5 + d = 23.08
Subtract 19.5 from both sides.
d = 3.58
11.70 + 7.80 + d = 23.08
d = 23.08 - 7.80 - 11.70
d = 3.58
To find the value of d in the equation 11.70 + 2*3.90 + d = 21.08 + 2.00, we need to isolate the variable d on one side of the equation.
First, let's simplify each side of the equation to make it easier to work with:
On the left side of the equation:
11.70 + 2 * 3.90 + d
= 11.70 + 7.80 + d
= 19.50 + d
On the right side of the equation:
21.08 + 2.00
= 23.08
Now, we can rewrite the equation with the simplified values:
19.50 + d = 23.08
Next, we want to isolate the variable d by getting rid of the constant term 19.50 on the left side of the equation. To do this, we can subtract 19.50 from both sides of the equation:
19.50 + d - 19.50 = 23.08 - 19.50
Simplifying further:
d = 3.58
So, the value of d in the equation is 3.58.
