Q. How many solutions does this equation have?−3s=−4s+6Choices:(A)no solution(B)one solution(C)infinitely many solutions
Add 4s: Add 4s to both sides of the equation to isolate the variable on one side.−3s+4s=−4s+4s+6s=6
Isolate the variable: Check the solution by substituting s=6 back into the original equation.−3(6)=−4(6)+6−18=−24+6−18=−18The solution s=6 satisfies the original equation.
