Given that,
a=b=5,
i.e. A=5 and b=5,
and also value of c is 20.
Now we put all values into following equation.
=> ax+b=c
=>5 x+5=20
=>5x=20-5
=>5 x=15
=> x=15/5
=> x=3.
Ans: The value of x is 3.
If ax+b=c, what is the value of x (e.g., a=b=5, c=20)?

X equals three. (5*3 = 15. 15 + 5 = 20)
A different approach involves subtracting 5 from both sides of the equation, then dividing the equation by 5. Afterwards, you are left with the value of X.
5x+5=20 (given)
5x=15 (subtract 5 from both sides)
x=3 (divide both sides by 5, get answer)
