Work out the value of a and b in the identity. 3ax + 6 - 4(x + b)= 11x + 14

a=5, b=-2

Step-by-step explanation:

If you simplify the equation, you get:

3ax +6 -4x -4b - 11x - 14 = 0 =>

3ax - 15x -4b -8 = 0

group together x's and constants:

(3a-15)x -8 -4b = 0

To make this 0 for all x, we have to find an a such that 3a-15 = 0 and b such that -8-4b = 0. this leads to a=5, b=-2

Cross-Multiply

(5x/2)*(5)=(3/1)*(11)

12.5x=33

Divide both sides by 12.5

12.5x/12.5=33/12.5

x=2.64

I hope that's help ! Please don't forget to write it as a fraction in lowest terms. I am totally don't remember . Good night .
