That one is super easy i believe you can get that !!
The answer you’re looking for is -5.
Plug in each possible value into the equation.
when m = 5
2k = m + 3
2k = (5) + 3
Simplify
2k = 8
isolate the k, divide 2 from both sides
2k/2 = 8/2
k = 8/2
k = 4
When m = 5, k = 4
-------------------------------------------------------------------------------------------------------------------
2k = m + 3
when m = 7
2k = (7) + 3
2k = 10
2k/2 = 10/2
k = 10/2
k = 5
when m = 7, k = 5
------------------------------------------------------------------------------------------------------------------
2k = m + 3
When m = 9
2k = (9) + 3
2k = 12
2k/2 = 12/2
k = 12/2
k = 6
when m = 9, k = 6
-------------------------------------------------------------------------------------------------------------------
hope this helps
Evaluate 5c-3d+115c−3d+115, c, minus, 3, d, plus, 11 when c=7c=7c, equals, 7 and d=8d=8d, equals, 8.

Answer:
use substitution
(5 x 7) - (3 x 8) + 11= 35 - 24 + 11= 22
