Answer:
x = -1.5
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
0.2x + 1 = 1.6x + 3.1
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 0.2x on both sides: 1 = 1.4x + 3.1
- Subtract 3.1 on both sides: -2.1 = 1.4x
- Divide both sides by 1.4: -1.5 = x
- Rewrite: x = -1.5
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitution: 0.2(-1.5) + 1 = 1.6(-1.5) + 3.1
- Multiply: -0.3 + 1 = -2.4 + 3.1
- Add: 0.7 = 0.7
Answer:
2.99
Step-by-step explanation:
<em>Note: [log10 = 1]</em>
<em> [log8 = 0.903089987]</em>
2log10 = 0.3010
<em> </em>22log8 = x
Therefore:
<em>2log10 x = 22log8</em>
<em>x = 2.99</em>

Answer:
x = 3/7
Step-by-step explanation:
Step 1:
6 - 2x = 3 + 5x Equation
Step 2:
6 = 3 + 7x Add 2x on both sides
Step 3:
3 = 7x Subtract 3 on both sides
Answer:
x = 3/7 Divide
Hope This Helps :)
Slope intercept form is y = 2x - 6
