You would add 3 on both sides
3x - 3 + 3 = 13 + 3
3x = 16
Answer:
10
Step-by-step explanation:
32 - (5 x 3 + 7) first do the multiplication - order of operations is important!
32 - (15 + 7) then combine the numbers in the parentheses
32 - 22 now subtract
10
Answer:
a4 x a
Step-by-step explanation:
factored by 2
By the confront theorem we know that the limit only exists if both lateral limits are equal
In this case they aren't so we don't have limit for x approaching 2, but we can find their laterals.
Approaching 2 by the left we have it on the 5 line so this limit is 5
Approaching 2 by the right we have it on the -3 line so this limit is -3
Think: it's approaching x = 2 BUT IT'S NOT 2, and we only have a different value for x = 2 which is 1, but when it's approach by the left we have the values in the 5 line and by the right in the -3 line.
