Question

What values of a and b in the equation shown, will result in an equation whose only solution is x=3?

-3/5 (x-5) +4x = ax+b

Answer 1

a=1 and b= 10.2 by adding and subtracting and converting 

Answer 2

Replace the value of x in the equation
-3/5(3-5)+4*3 = 3a+b
6/5 + 12 =3a+b
66/5=3a+b
66=15a+5b
a=1 and b=10.2
