Answer 1

We have the original equation:

7x + 3 = 52

Isolate the variable x by subtracting 3 to both sides of the equation:

7x+3-3=52-3

Simplify the previous expression:

7x+0=49 or 7x = 49

Isolate the variable x dividing by 7 to both sides of the equation:

(7/7)x = 49/7

Simplify the previous expression, and finally, we have:

x = 7.
