Answer:
x = 12
Step-by-step explanation:
Given the expression
we are to find the value of x;
Step 1; Rearrange the equation:

Step 2: subtract 5 from both sides of the equation:

Step 3: Find the value of x:

Hence the solution to the equation is 12 not -72
As we know only square of 4 and 6 having 6 as unit digit. All the other digit doesn't have 6 in unit digit of two digit number.
Square of 4 is =

Square of 6 is =

So the possible value for tenth digit is 1 and 3.
Well first you wanna simplify both sides so..
5+5t=2t+23 you then wanna isolate the variable so...
3t=18 divide by 3 and ...
t=6
14= 7+7
16= 8+8
18= 9+9
20= 9+11
22= 10+12
24= 12+12
26= 7+8+11
