<u>Algebra I</u>

  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -7x + 6

y = -10x

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em> [1st Equation]:                                                                           -10x = -7x + 6
  2. [Addition Property of Equality] Add 7x on both sides:                                   -3x = 6
  3. [Division Property of Equality] Divide -3 on both sides:                                x = -2

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Substitute in <em>x </em>[2nd Equation]:                                                                         y = -10(-2)
  2. Multiply:                                                                                                             y = 20

1) Substitute y for y in the equation and set them equal to each other.

-10x=-7x+6

*Combine like terms*

2) add 7x to both sides

-3x=6

*isolate x: divide by -3*

3) x=-2

Va rog sa ma ajutați: 420/180x54/180
MAVERICK [17]
First, you want to divide 420 by 180. Then, divide 54 by 180. Lastly, you want to multiply the answers of the two together.
                    - 
420/180= 2.3 

54/180= 0.3

2.3 * 0.3 = 0.69

*You just take it step by step. Hope I helped. :)
