Y=2x+5 and y=3x+2 using substitution strategy
WINSTONCH [101]

Answer:

Hi there the answer will be (3,11)

Since you are using the substitution way, you first plug in one of the y's into the other equation and you can see that they are set equal to each other.

2x+5=3x+2

Then you subtract 2x on both sides to get the x's on the same side

and you get 5=x+2

Then you subtract 2 on both sides, and you get x to equal to 3

then you plug x into any equation to get y to equal 11

y= 2(3)+5

  3. Exponents
  4. Multiplication
  5. Division
  6. Addition

  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle \frac{a}{-7} - 7 = 5<u />

<u />

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

  1. Addition Property of Equality:                    \displaystyle \frac{a}{-7} - 7 + 7 = 5 + 7
  2. [Simplify] Add:                                             \displaystyle \frac{a}{-7}= 12
  3. Multiplication Property of Equality:           \displaystyle -7 \cdot \frac{a}{-7} = 12 \cdot -7
  4. [Simplify] Multiply:                                      \displaystyle a = -84

<u>Step 3: Check</u>

<em>Plug in a into the original equation to verify it's a solution.</em>

  1. Substitute in <em>a</em>:                    \displaystyle \frac{-84}{-7} - 7 = 5
  2. [Frac] Divide:                       \displaystyle 12 - 7 = 5
  3. Subtract:                              \displaystyle 5 = 5

Here we see that 5 does indeed equal 5.

∴ a = -84 is the solution to the equation.
