10b plus 18= 28 What is b

b = 0

B would be one 10 x 0 is zero, resulting in the problem just being eight

Actually, the answer would be 8.

When we subtract 18 from both sides of the equation, we have:

10b + 18 - 18 = 28 - 18
10b = 10

Then, when we divide both sides by 10:

b = 10/10
b = 1

So, b would be equal to 1.

-90 = -6*a - 12

What is a

To solve for a, we can start by isolating the term -6a on one side of the equation. We can do this by adding 12 to both sides:

-90 + 12 = -6a - 12 + 12
-78 = -6a

Next, we can divide both sides by -6 to solve for a:

-78 / -6 = -6a / -6
13 = a

Therefore, a is equal to 13.

-98= 4*x - 50

What is x

To solve for x, we can isolate the term 4x on one side of the equation. We can do this by adding 50 to both sides:

-98 + 50 = 4x - 50 + 50
-48 = 4x

Next, we can divide both sides by 4 to solve for x:

-48 / 4 = 4x / 4
-12 = x

Therefore, x is equal to -12.
