Y = 4x - 3
2x + 7y = 41

We need to substitute the first equation into the second equation. So, we would substitute y in the second equation with 4x -3.

2x + 7(4x -3) = 41

This would be answer choice C. 2x + 7(4x - 3) = 41.

Solving by substitution:

y = 4x - 3 

2x + 7y = 41

Let us substitute the first equation y = 4x - 3  into the second.

2x + 7y = 41

2x + 7(y = 4x -3) = 41

2x + 7(4x -3) = 41

So that's the third option.

I hope this helps.

2(4-8x)+6=-1 interpreting experiessions
Anestetic [448]

Answer:

X = \frac{13}{16}

Step-by-step explanation:

2 (4-8x) + 6 = 1

Multiply parentheses by 2

8 - 16x + 6 = 1

add (8 + 6)

14 - 16x = 1

Move constant to right and change its sign

-16x = 1 -14

Calcualte te difference

-16x = -13

divide bot sides by -16

x = \frac{13}{16}
