Answer:

a=10

b=-8

Step-by-step explanation:

[tex]2(5x-4)=ax+b[/tex]

[tex]10x-8=ax+b[/tex]

a=10

b=-8

It's simple. I need my x variable to have a positive coefficient, 10 is already positive; therefore, I simply conclude a = 10. B has to be negative, but in the equation is positive (+b) therefore I need a negative number to make b negative when multiplied (-*+)

Answer:

2(5x-4) = ax+b

10x-8 = ax+b (Both sides are in the same format so you can substitute in the values)

a =10

b = -8
