Explanation:
Picture
Answer:
y = 
+ 6
Step-by-step explanation:
you need another equation to solve them simultaneously since they are two unknown
Answer:
B
Step-by-step explanation:
when you subtact 3y on both sides
you get x = -3y+4
Answer:
1 solution.
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define equation</u>
9(z + 8) = -9z - 72
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 9: 9x + 72 = -9z - 72
- Add 9z to both sides: 18z + 72 = -72
- Subtract 72 on both sides: 18z = -144
- Divide 18 on both sides: z = -8
Here we see that we will get only 1 solution for <em>z</em>.
