Anna71 [15]

<u>Part 1)</u> "Four times the difference of a number and $7$ is $32$ "

Let

x--------> the number

we know that

the expressions is equal to

$4(x-7)=32$

therefore

<u>the answer part 1) is</u>

$4(x-7)=32$

<u>Part 2)</u> "One third of a number is $12$ less than the number itself"

Let

x--------> the number

we know that

the expressions is equal to

$\frac{1}{3} x=(x-12 )$

therefore

<u>the answer part 2) is</u>

$\frac{1}{3} x=(x-12 )$

<u>Part 3)</u> "Ten increased by the quotient of a number and $2$ is $-15$ "

Let

x---------> the number

we know that

the expressions is equal to

$10+ (\frac{x}{2} )= -15$

therefore

<u>the answer Part 3) is</u>

$10+ (\frac{x}{2} )= -15$

<u>Part 4)</u> "One less than the product of a number and $3$ is $5$ more than the number itself"

Let

x---------> the number

we know that

the expressions is equal to

$(3x)-1=5+x$

therefore

<u>the answer Part 4) is</u>

$(3x)-1=5+x$
