38+7k=8(k+4)
3(1-3x)=2(-4x+7)

K = 6      X = -11

Step-by-step explanation:

38+7k=8(k+4)                  3(1-3x)=2(-4x+7)

38 + 7k = 8k + 32               3 - 9x = - 8x + 14

     - 7k    -7k                    - 3                   -  3

 38 = k + 32                        -  9x = - 8x + 11

- 32      - 32                         + 8x   + 8x

        k = 6                             - 1x = 11

                                               -1     -1

                                                x = -11

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
