Answer:
passed: 164
failed: 41
Step-by-step explanation:
Let the failed students be x, then the passed students will be 4x.
x + 4x = 205
x = 205/5 = 41
4x = 4*41 = 164

Answer:
x = -1
Step-by-step explanation:
<u>Step 1: Combine like terms on the right side
</u>
6 - 8x = 7x - 9x + 12
6 - 8x = -2x + 12
<u>Step 2: Add 8x to both sides
</u>
6 - 8x + 8x = -2x + 12 + 8x
6 = 6x + 12
<u>Step 3: Subtract 12 from both sides
</u>
6 - 12 = 6x + 12 - 12
-6 = 6x
<u>Step 4: Divide both sides by 6
</u>
-6 / 6 = 6x / 6
-1 = x
Answer: x = -1
-15-(-18)=-15 +(-18)=-33
-×-=+ +×-= -
-15×-(-18)= 3
-15×+(-18)=-33
3-33=-33
-30=-30
