Answer:

x = 5\frac{1}{4}

Step-by-step explanation:

5(x - 3\frac{3}{4} ) = 7\frac{1}{2}

Use distributive property

5x - 18\frac{3}{4} = 7\frac{1}{2}

Add 18\frac{3}{4} to both sides

5x = 26\frac{1}{4}

Divide both sides by 5

x = 5\frac{1}{4}

What are the solutions to the quadratic equation 3(x – 42 = 752
Neporo4naja [7]
X=292.6

Step 1: distribute 3 through parentheses
3x-126=752

Step 2: move the constant to the right and change it sign
3x= 752+126

Step 3: add the numbers
3x= 878

Step 4: divide both sides by three
X= 878/3 or 292.6

Equality Properties

Step-by-step explanation:

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

5x + 2 = 20

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

  1. Subtract 2 on both sides:                    5x = 18
  2. Divide 5 on both sides:                        x = 18/5

<u>Step 3: Check</u>

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

  1. Substitute in <em>x</em>:                    5(18/5) + 2 = 20
  2. Multiply:                               18 + 2 = 20
  3. Add:                                     20 = 20

Here we see that 20 does indeed equal 20.

∴ x = 18/5 is a solution to the equation.
