Linear Equations in One Variable

SAT Math· difficulty 5/5

The equation kx+32=4x+1\frac{kx + 3}{2} = 4x + 1 has no solution. What is the value of kk?

  • A

    1

  • B

    Any value 8\ne 8

  • C

    8

    check_circle
  • D

    8-8

Explanation

Multiply by 2: kx+3=8x+2kx + 3 = 8x + 2. For no solution: k=8k = 8 and 323 \ne 2 (which holds). So k=8k = 8.
