You cross multiply, the solve for #x#

Explanation:

Assuming you have to solve for #x#,
You would do #2x# + 4 ⋅ 6 and #x# +4 ⋅ 5, then make them equal each other

So,
#12x# + 24 = #5x# + 20

Then put all the variables on one side and numbers on the other.
#12x# - #5x# = 20 - 24

#7x# = -4

Then solve for #x#,
#x# = #-4/7#
