There is no other equations
Answer:
zero
Step-by-step explanation:
because when u equate both equation ,
-2x-5= -2x+7
or, -2x+2x=7+5
or, 0=12
which is invalid so it has no solution
12(3-2x) = 84
do distributive multiplication:
12(3) + 12(-2x) = 84
36 - 24x = 84
Deduct 36 to both sides
36 - 36 - 24x = 84 - 36
-24x = 48
divide -24 to both sides
-24x / -24 = 48/-24
x = -2
To check:
12(3-2x) = 84
12(3-2(-2) = 84
12(3+4) = 84
12(7) = 84
84 = 84
