Isolate variable j: First, we want to isolate the variable j on one side of the equation. To do this, we will move the term −310 to the other side by adding 310 to both sides of the equation.−31+310=4j−310+310
Combine like terms: Now, we combine the like terms on the left side of the equation.−31+310 = 4j39 = 4j3=4j
Find value of j: To find the value of j, we need to multiply both sides of the equation by 4.3×4=4j×412=j
