Question

(d+4):(23-19)=20 рівняння

Answer 1

(d+4):(23-19) = 20
(d+4): 4 = 20
d + 4 = 80
d= 76

Answer 2

To solve the equation (d+4):(23-19) = 20, we can follow these steps:

1. Simplify the expression on the left side of the equation: (d+4):(23-19) = (d+4):4

2. Apply the division operation to the expression: (d+4):4 = 20

3. Multiply both sides of the equation by 4 to eliminate the division: 4 * (d+4):4 = 20 * 4 d + 4 = 80

4. Subtract 4 from both sides of the equation to isolate the variable d: d + 4 - 4 = 80 - 4 d = 76

Therefore, the solution to the equation (d+4):(23-19) = 20 is d = 76.
