Explanation:
Calcium ions play an important role in cardiac muscle physiology. Calcium ions influx is responsible for plateau phase after depolarization. Calcium ions also play role in muscle contraction with the help of troponin (regulatory protein).
For contraction, about 20 percent of calcium ions are supplied from outside of the cell, while rest of the calcium ions are released from SR (sarcoplasmic reticulum).

Let's solve your equation step-by-step.
x−98+877=654
Step 1: Simplify both sides of the equation.
x−98+877=654
x+−98+877=654
(x)+(−98+877)=654(Combine Like Terms)
x+779=654
x+779=654
Step 2: Subtract 779 from both sides.
x+779−779=654−779
x=−125
Answer:
x=−125
