Q. What value of a is a solution to this equation?13+a=19Choices:(A)a=6(B)a=7
Perform Inverse Operation: To isolate the variable a, we need to perform the inverse operation of addition on both sides of the equation. Since 13 is added to a, we should subtract 13 from both sides to find the value of a.Calculation: 19−13=6
Subtract 13: Now that we have performed the subtraction, we can see that a=6.
