You can put this solution on YOUR website! x=-3s,x=10-4s
Replace all occurrences of x with the solution found by solving the last equation for x. In this case, the value substituted is -3s.
x=-3s_(-3s)=-4s+10
Remove the parentheses around the expression -3s.
x=-3s_-3s=-4s+10
Since -4s contains the variable to solve for, move it to the left-hand side of the equation by adding 4s to both sides.
x=-3s_-3s+4s=10
Since -3s and 4s are like terms, subtract 4s from -3s to get s.
x=-3s_s=10
Replace all occurrences of s with the solution found by solving the last equation for s. In this case, the value substituted is 10.
x=-3(10)_s=10
Multiply -3 by each term inside the parentheses.
x=-30_s=10
This is the solution to the system of equations.
x=-30_s=10
