How many solutions does this equation have? 9j − 7 = 10j Choices: (A)no solution (B)one solution (C)infinitely many solutions

Isolate variable j: Isolate the variable j on one side of the equation. To do this, we can subtract 9j from both sides of the equation to get: 9j - 7 - 9j = 10j - 9j This simplifies to: -7 = jCheck for errors: Check for any mathematical errors in the previous step. Subtracting 9j from both sides was done correctly, but the simplification was incorrect. The correct simplification should be: -7 = 10j - 9j Which simplifies to: -7 = j
