Reflection: Linear Equation

Today I Worked on Linear Equations, The Problem Was:

  • =27
  • y+=6

I started by adding 2 and 5 and subtracting -3 from +3 and subtracting -27 and 6

so i’m left with:

7 y = -21

Now divide

  • 7 y = -21
  • 7    = 7

y = -3

Now you plug in the -3 for the Y so:

  • 5(-3) + 3 x = 6
  • -15 + 3 x = 6
  • +15          +15

And you’re left with :

3 x= 21

Now divide:

  • 3 x = 21
  • 3   =   3

Now divide and your left with

X= 7

so the answers are:

X=7

Y=-3

I’m checking what type of design ill use for the car for derby racing
