step-by-step explanation:

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.
