Answer:
2 2/5
Step-by-step explanation:
5/6 x-4 = -2
Add 4 to each side
5/6 x-4+4 = -2+4
5/6 x = 2
Multiply by 6/5 to isolate x
6/5 *5/6 x = 6/5 *2
x = 12/5
Changing this from an improper fraction
5 goes into 12 2 times with 2 left over
x = 2 2/5
That would be step 2.
step 1 is correct....multiplying the first equation by -6 which gives you :
-6y = -24 + 12z
but in step 2, the simplifying would be : y = 4 - 2z
