Step 1: Subtract 25 to both sides. This will cancel 25 on the left side and bring it over to the right

(25 - 25) - 3x = 40 - 25

(0) - 3x = 15

-3x = 15

Step 2: Isolate x by dividing -3 to both sides (the opposite of multiplication is division).

-3x ÷ (-3) = 15 ÷ (-3)

x = -5

Check:

25 - 3(-5) = 40

25 + 15 = 40

40 = 40 ....................................Correct!
