[ Answer ]
[tex]\boxed{X \ = \ 8.4}[/tex]
[ Explanation ]
- Find X In Equation: 4x + 8y = 40
Y = 0.8
X = ?
--------------------------------------
- Rewrite Equation Using 0.8
4x + (8 · 0.8) = 40
- Multiply The Numbers: 8 · 08 = 6.4
4x + 6.4 = 40
- Subtract 6.4 From Both Sides
4x + 6.4 - 6.4 = 40 - 6.4
- Simplify
4x = 33.6
- Divide Both Sides By 4
[tex]\frac{4x}{4}[/tex] = [tex]\frac{33.6}{4}[/tex]
- Simplify
X = 8.4
[tex]\boxed{[ \ Eclipsed \ ]}[/tex]
Answer:
x = 8.4
Step-by-step explanation:
4x + 8y = 40
4x + 8 (.8) = 40
4x + 6.4 = 40
4x = 33.6
