Answer:
Step-by-step explanation:
Okay, take for example:
1+2=3 is the same as 1=3-2
See how we changed the place of the 2. We can do that as long we change + to - and vica versa.
Let's see your example:
6+y=-8
We move the 6 on the other side of the expression with the opposite sign (it is a rule) and we get:
y=-8-6
y=-14
The answer to your question is
86+y=99
y=99-86
y=13

B) BD
Step-by-step explanation:
The number of columns of the first matrix (2nd dimension) must match the number of rows of the second matrix (1st dimension). When you write the dimensions together, the two middle numbers must be the same.
AB ⇒ (3x2) × (3x5) . . . . 2 ≠ 3, so cannot be multiplied
BD ⇒ (3x5) × (5x7) . . . . 5 = 5, so can be multiplied
CD ⇒ (2x3) × (5x7) . . . . 3 ≠ 5, so cannot be multiplied
DD ⇒ (3x5) × (3x5) . . . . 3 ≠ 5, so cannot be multiplied
