Y = 5x -30
I believe this is what you needed
Answer:
x∈[20/3;+∝).
Step-by-step explanation:
3x+10≥30; ⇔ 3x≥20; ⇔ x≥20/3

Answer:
x = infinite amount of solutions
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
4x - 3y = 1
-8x + 6y = -2
<u>Step 2: Rewrite systems</u>
-8x + 6y = -2
- Add 8x to both sides: 6y = 8x - 2
- Divide 6 on both sides: y = 4/3x - 1/3
<u>Step 3: Redefine systems</u>
4x - 3y = 1
y = 4/3x - 1/3
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 4x - 3(4/3x - 1/3) = 1
- Distribute -3: 4x - 4x + 1 = 1
- Combine like terms: 1 = 1
Here we see that 1 does indeed equal 1.
∴ x = all real numbers/infinite amount of solutions
<u>Step 5: Graph</u>
<em>Check the systems.</em>
We see that the 2 equations are the same line.
