j=-4/5k+6/5 k=-5/4j+3/2
Step-by-step explanation:
Let's solve for j.
15j+12k=18
Step 1: Add -12k to both sides.
15j+12k+−12k=18+−12k
15j=−12k+18
Step 2: Divide both sides by 15.
15j

=
−12k+18

Let's solve for k.
15j+12k=18
Step 1: Add -15j to both sides.
15j+12k+−15j=18+−15j
12k=−15j+18
Step 2: Divide both sides by 12.
12k

=
