Isolate variable j: First, we need to isolate the variable j on one side of the equation.j+49=4Subtract 49 from both sides to get j by itself.j+49−49=4−49j=4−49
Subtract 49: Now, we need to perform the subtraction on the right side of the equation.Since 4 is the same as 416, we can write it as:j=416−49Now subtract the numerators and keep the denominator the same.j=416−9j=47
