Step-by-step explanation:
Multiply the density of the liquid or gas by how deep in the tank you want to calculate the pressure. For example, assume you have water with a density of 60 lb. mass per square foot (lbm/ft²) and you want to find the pressure 10 feet down the tank. So, 60 lbm/ft² times 10 feet equals 600 lbf/ft².

3x+7=-x-1
move -x to the other side
sign changes from -x to +x
3x+x+7=-x+x-1
3x+x+7=-1
4x+7=-1
move 7 to the other side
sign changes from +7 to -7
4x+7-7=-1-7
4x=-8
Divide by 4 for both sides
4x/4=-8/4
Answer: x=-2
