Explanation:
so let the unknown be x
x+5-3=17
x+2=17
so then you carry +2 over to the left hand side which collecting of like terms
so we have
x=17-2
x=15
so therefore the unknown value x is 15
to check
we substitute 15 for x in the equation
let's go
so we have
15+5-3=17
now using this solve it .
I believe u can do it
or I just do it
so we hv the unknown to be x
x*5-3=17
5x-3=17
5x=17+3
5x=20
x=20/5
x=4
