Can anyone solve for j: 7(j + 4) = -60

7(j+4)=7j+28=-60
subtract 28 from both sides
7j=-88
j=-12.57

This question is asking you to find the value of j, to do so you have to isolate or leave alone j by doing different mathematical operations according to the given equation.

The given equation is 7(j+4)=-60, the first step to solve this equation would be distribute, next subtract, and last divide.

7(j+4)=-60              Distribute 7 into the parenthesis
 7j+28=-60              Subtract 28 in both sides
       7j=-88              Divide by 7 to isolate j
         j=-12.57

The value of j in this equation is around -12.57.

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
