To solve a equation in R, you can use **solve()** function in R. This function takes two main arguments: the coefficients of the equations and the right-hand side values.

The following method shows how you can do it with syntax.

**Method 1: Use solve() Function**

```
solve(coefficients, RHS_values)
```

The following example shows how to use **solve()** function to solve equation in R.

## Using solve() Function

Let’s see how we can use **solve()** function in R:

```
# Declare coefficients matrix
coe_mat <- matrix(c(10,3,8,-5,-10,5,7,-10,2), nrow=3,byrow = TRUE)
# Declare right hand side values
v <- c(30,20,10)
# Solve equation
s <- solve(coe_mat,v)
# Print solved equation
print(s)
```

Output:

```
[1] 0.09318996 -0.19354839 3.70609319
```

Here the output shows values of solved equation that we declare in above code.
