Solve for j j .\newlinej2+7=12j= \begin{array}{l} \frac{j}{-2}+7=-12 \\ j=\square \end{array}

Full solution

Q. Solve for j j .\newlinej2+7=12j= \begin{array}{l} \frac{j}{-2}+7=-12 \\ j=\square \end{array}
  1. Isolate j term: First, we will focus on the equation j2+7=12\frac{j}{-2} + 7 = -12 and isolate the term containing jj.
    j2+7=12\frac{j}{-2} + 7 = -12
    Subtract 77 from both sides to isolate the term with jj.
    j2+77=127\frac{j}{-2} + 7 - 7 = -12 - 7
    j2=19\frac{j}{-2} = -19
  2. Multiply by 2-2: Now, we will multiply both sides by 2-2 to solve for jj.j2×(2)=19×(2)\frac{j}{-2} \times (-2) = -19 \times (-2)j=38j = 38
  3. Fill in the square: Since the second part of the system of equations is simply j=j=\square, we can fill in the square with the value we found for jj.j=38j = 38
