  2. 35
  3. 9/2

Explanation:

Hi student! Let me help you out on this question.

_____________


\dag SOLVING EQUATIONS
\dag

In the first equation, we can add up the x's and then solve.


\boldsymbol{x+x+x=54}


\boldsymbol{3x=54}.

Next, divide both sides by 3.


\mid\overline{\underline{\boldsymbol{18}}}\mid

Problem Solved!

_________

Here we should multiply both sides by 5.


\boldsymbol{\cfrac{y}{\\ot5}\cdot \\ot5=7\cdot5}

On the left, the 5's cancel, and we are left with y.

On the right we have 7*5, which is 35.


\therefore,


\boldsymbol{y=35}

____________

Here we should subtract 6 from both sides.


\boldsymbol{4t+6-6=24-6}


\boldsymbol{4t=18}

Next, divide both sides by 4.


\boldsymbol{t=\cfrac{18}{4}}. This fraction can be reduced, if we divide the numerator, 18, and the denominator, by 2:


\boldsymbol{t=\cfrac{9}{2}}. Which is our answer, written as an improper fraction.

Written as a mixed number ↓


\boldsymbol{4\cfrac{1}{2}}

Written as a decimal:


\boldsymbol{t=4.5}

Hope that this helped! Best wishes.

Exercise number 1

  • x + x + x = 54

Combine x and x to get 2x.

  • 2x + x = 54

Combine 2x and x to get 3x.

  • 3x = 54

Divide both sides by 3.

  • x = 54 / 3

Divide 54 by 3 to get 18.

  • x = 18 ===> Answer

Verification

Let x=18.

  • 18 + 18 + 18 = 54
  • 36 + 18 = 54
  • 54 = 54

Checked ✅

Exercise number 2

  • y / 5=7

Multiply both sides by 5.

  • y = 7 x 5

Multiply 7 and 5 to get 35.

  • y = 35 ===> Answer

Verification

Let y=35.

  • 35 / 5 = 7
  • 7 = 7

Checked ✅

Exercise number 3.

  • 4t + 6 = 24

Subtract 6 from both sides.

  • 4t= 24 - 6

Subtract 6 from 24 to get 18.

  • 4t =18

Divide both sides by 4.

  • t = 18 / 4

Reduce the fraction 18/4 to its lowest expression by extracting and canceling 2.

  • t = 9 / 2 ===> Answer

Verification

Let t = 9/2.


  1. \sf{4*(9)/(2)+6=24 }

  2. \sf{(4*9)/(2)+6=24 }

  3. \sf{(36)/(2)+6=24 }

  4. \sf{18+6=24 }

  5. \sf{24=24}

Checked ✅
