Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

-x + 5y = -4

4x + 3y = 16

Step 2: Rewrite systems

x = 5y + 4

4x + 3y = 16

Step 3: Solve for y

Substitute in x:                              4(5y + 4) + 3y = 16Distribute 4:                                   20y + 16 + 3y = 16Combine like terms:                     23y + 16 = 16Subtract 16 on both sides:           23y = 0Divide 23 on both sides:              y = 0

Step 4: Solve for x

Define:                              4x + 3y = 16Substitute in y:                 4x + 3(0) = 16Multiply:                            4x = 16Isolate x:                            x = 4

And we have our final answer!

1. 
(100 + d^2)(d + 10)(d - 10)

Use the rule of splitting perfect squares to get the factors. 

2. 
x^4y^8z^2(x^2z^6 - y)

The first term is the greatest common factor.
