Evaluate the expression for
a = 26, b = 10, c = 9, d = 19:
a+b-c-d

8

Step-by-step explanation:

a+b-c-d

lets substitute the values of a, b, c and d in the equation:

26+10-9-19

so we have:

8

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
