Q. How many solutions does this equation have?9j=8j+4Choices:(A)no solution(B)one solution(C)infinitely many solutions
Isolate variable j: Isolate the variable j on one side of the equation.9j−8j=8j+4−8jThis simplifies to:j=4
Check solution j=4: Check if the solution j=4 satisfies the original equation.Substitute j=4 into the original equation:9(4)=8(4)+436=32+436=36This shows that j=4 is a solution to the equation.
Determine number of solutions: Determine the number of solutions. Since we found a specific value for j that satisfies the equation, and there are no other possible values for j that would satisfy the equation, there is only 1 solution.
