1/4(z +3z)+ 7=−z + 1 please help with this ive been stuck
erastovalidia [21]

Answer:

<em><u>z = -3</u></em>

Step-by-step explanation:

<u>Step 1: Simplify both sides of the equation. </u>

z+7=−z+1

<u>Step 2: Add z to both sides. </u>

z+7+z=−z+1+z

2z+7=1

<u>Step 3: Subtract 7 from both sides. </u>

2z+7−7=1−7

2z=−6

<u>Step 4: Divide both sides by 2. </u>

<u>2z</u>   =  <u>−6 </u>

2      2

z=−3

Then, she drank one more 3/5 cup of milk. Then you add all the whole numbers, which equals 3 then you have that 3/5 left over so its 3 3/5
