Question

Consider the equation 4+2(5x-8) = ax +b.

For what values of a and b would the equation have infinitely many solutions?

Answer 1

a = 10, b = -12

Explanation:

4+2(5x-8) = ax +b

4 + 10x - 16 = ax + b

10x - 12 = ax + b

Infinitely many solutions when:

a = 10

b = -12

Answer 2

a= 10

b = -12

Explanation:

4+2(5x-8) = ax +b.

4+10x-16 = ax + b

4-16+10x = ax+b

-12+10x= ax+b

10x+(-12)= ax+b

ax= 10x

a= 10

b = -12
