Answer:

2a - b

Step-by-step explanation:

First combine like terms.

(16a + 20a) - 18b

36a - 18b

This can be simplified by dividing the expression by 18

\frac{36a}{18} - \frac{18b}{18}

2a - b

What value of b will cause the system to have an infinite
kvasek [131]

Hi there!

The way that an infinite number of solutions is achieved is when the two equations, when solved together, get an answer which is just a number equal to the same number. To do this, first substitute 6x-b in for y in the second equation.

-3x+\frac{1}{2}(6x-b)=-3

-3x+3x-\frac{1}{2}b=-3

-\frac{1}{2}b=-3

Now, we see that b needs to be equal to -3 when multiplied by -1/2. When both sides are divided by -1/2, b becomes equal to 6. Thus, b must be 6.

Check work:

6x-6=y

-3x+\frac{1}{2}(6x-6)=-3

-3x+3x-3=-3

-3=-3

Thus, as they are equal to each other, the answer is correct. b = 6.

Hope this helps!
