Answer: 7/4
Step-by-step explanation:
you would first add 5 to both sides
4x-5+5= -12+5
then simplify
4x= -7
divide 4 on both sides
4x/4= -7/4
and you get x=7/4
Answer:
The answer to your question is:
x = 2
y = 4
4x - 5y = -12 (1)
-x + 5y = 18 (2)
Solve the system
4x - 5y = -12
-x + 5y = 18
3x + 0 = 6
3x = 6
x = 6 / 3
Substitution
4(2) - 5y = -12
8 -5y = -12
-5y = -12 - 8
-5y = -20
y = -20 / -5
