Final answer:
To solve for j, subtract 10.2j from both sides of the equation. Then subtract 8 from both sides. Finally, divide both sides by 2.4 to find j.
Step-by-step explanation:
To solve for j in the equation 12.6j+8=10.2j+4.4, we need to isolate the variable j on one side of the equation. To do this, we can subtract 10.2j from both sides to get: 12.6j+8-10.2j=10.2j+4.4-10.2j. Simplifying this gives us 2.4j+8=4.4. Then, we can subtract 8 from both sides to get 2.4j+8-8=4.4-8, which simplifies to 2.4j= -3.6. Finally, we can divide both sides by 2.4 to solve for j: (2.4j)/2.4= -3.6/2.4. This gives us j= -1.5.
