Question

Which shows the correct solution of the equation a+b=50, when a = 30?

a. 1056
b. 20 - 50
c. (a+20) - 20 = 50 - 20
d. 24 = 30

Answer 1

To solve the equation a + b = 50 when a = 30, substitute the value of a and simplify the equation to find b = 20 as the solution.

Step-by-step explanation:

The correct solution of the equation a + b = 50 when a = 30 is found by substituting the value of a into the equation. This step looks like:

30 + b = 50.

To find the value of b, we subtract 30 from both sides of the equation:

b = 50 - 30,

b = 20.

Therefore, the correct solution is b = 20.
