Answer:

c=2

Step-by-step explanation:

hope it helps :)

Simplifying

3 + -1(2c + -8) = 7

Reorder the terms:

3 + -1(-8 + 2c) = 7

3 + (-8 * -1 + 2c * -1) = 7

3 + (8 + -2c) = 7

Combine like terms: 3 + 8 = 11

11 + -2c = 7

Solving

11 + -2c = 7

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-11' to each side of the equation.

11 + -11 + -2c = 7 + -11

Combine like terms: 11 + -11 = 0

0 + -2c = 7 + -11

-2c = 7 + -11

Combine like terms: 7 + -11 = -4

-2c = -4

Divide each side by '-2'.

c = 2

Simplifying

c = 2

Hich value, when placed in the box, would result in a system of equations with infinitely many solutions?
Jobisdone [24]

The value placed in the box that makes the system of equation with infinitely many solution is 12.

<h3>How to solve an infinitely many solution equation?</h3>

An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16.  If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.

Hence,

y = -2x + 4

Therefore,

6x + 3y = 12

divide the equation(ii) by 3

2x + y = 4

y = -2x + 4

Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.
