How to solve system of equations
5a=5
6b-3c=15
2a+7c=-5

  • Math 11th grade -

    from the first
    a = 1
    replace a with 1 in the third that will give you c
    then put the value of c into the 2nd to get b

  • Math 11th grade -

    first we will find the value of a that is a=1 tan we will put the value of a in eq3 to find c so on we wil find b by putting the value of c in eq2.
