Zoe Meyers · Answer 1

x = 3

Step-by-step explanation:

7^ (x-2) = 7¹

Equate powers

x-2 = 1

x = 3

Tania Short · Answer 2

x=3

Step-by-step explanation:

7^x-2=7

7 is equal to 7^1 as it is equals to 7

7^x-2=7^1

eliminating the powers

x-2 = 1

add 2 to both sides

x = 1+2 = 3

lets check the answer

7^x-2=7

7^3-2=7

7^1 = 7

7=7

LHS = RHS
