substitution calculator

Today let me hlep you on substitution calculator. when we study on substitution .... it plays am importance steps towards it. Keep reading let me help you with the following example..

Determine the following system of the linear equations using the method of substitution calculator.

x - y = -5 --------------------(1)

3x+8y = -48-----------------(2)

Sol:

Step 1: Rearrange the first equation,

x - y = -5

y = x + 5---------------------(3)

Step 2: Substitution this value in for y =x + 5 into the second equation;

3x + 8(x + 5) = -48 This could also help us on factoring polynomial calculator

Step 3:Expand and simplify the equation:

3x + 8x + 40 = -48

11x = -88

x = -8-----------------------(4)

Step 4:Substitution of the value x back into the one of that original equations;

-8 - y = -5

! y = -3----------------------------(5)

The required answer are x = -8, y = -3
