Answer:

x = -9

Step-by-step explanation:

<em>To solve the equation</em>

  • Simplify each side
  • Separate the variable on one side and the numerical term on the other side
  • Make the coefficient of the variable equal 1

<em>Let us do these steps with our question to find x</em>

∵ 4(2x + 7) = 12 - 2(10 - 2x)

→ Simplify each side

∵ 4(2x) + 4(7) = 12 - 2(10) - 2(-2x)

∴ 8x + 28 = 12 - 20 + 4x

→ Add the like terms in the right side

∵ 8x + 28 = (12 - 20) + 4x

∴ 8x + 28 = -8 + 4x

→ Subtract 28 from both sides

∵ 8x + 28 - 28 = -8 - 28 + 4x

∴ 8x = -36 + 4x

→ Subtract 4x from both sides

∵ 8x - 4x = -36 + 4x - 4x

∴ 4x = -36

→ Make coefficient of x equal 1 by dividing both sides by 4

∴ \frac{4x}{4}=\frac{-36}{4}

∴ x = -9

Nine less than one forth of a number is 6
snow_lady [41]

Answer:

x = 60

Step-by-step explanation:

<u>Step 1:  Convert into an equation</u>

Nine less than one forth of a number is 6

1/4x - 9 = 6

<u>Step 2:  Add 9 to both sides</u>

1/4x - 9 = 6

1/4x - 9 + 9= 6+ 9

1/4x = 15

<u>Step 3:  Multiply both sides by 4</u>

1/4x * 4 = 15 * 4

x = 60

Answer:  x = 60
