1. Given the equation [tex][tex]$2x + 4y = 25$[/tex][/tex], solve for [tex]x[/tex] when [tex]x = 6[/tex] and [tex]y = 8[/tex].

Sagot :

To solve the equation [tex]\( 2x + 4y \)[/tex] when [tex]\( x = 6 \)[/tex] and [tex]\( y = 8 \)[/tex], follow these steps:

1. Identify the values of [tex]\( x \)[/tex] and [tex]\( y \)[/tex]:
- [tex]\( x = 6 \)[/tex]
- [tex]\( y = 8 \)[/tex]

2. Substitute the values of [tex]\( x \)[/tex] and [tex]\( y \)[/tex] into the equation [tex]\( 2x + 4y \)[/tex]:
- Replace [tex]\( x \)[/tex] with 6
- Replace [tex]\( y \)[/tex] with 8

3. Perform the multiplication:
- Calculate [tex]\( 2 \times 6 \)[/tex]:
[tex]\( 2 \times 6 = 12 \)[/tex]
- Calculate [tex]\( 4 \times 8 \)[/tex]:
[tex]\( 4 \times 8 = 32 \)[/tex]

4. Add the results from the multiplications:
- [tex]\( 12 + 32 = 44 \)[/tex]

Therefore, the value of the expression [tex]\( 2x + 4y \)[/tex] when [tex]\( x = 6 \)[/tex] and [tex]\( y = 8 \)[/tex] is [tex]\( 44 \)[/tex].
Given the equation the answer is 44
