M(x)=5x-5
this is like y=5x-5
to find inverse swap x and y and solve for y
x=5y-5
x+5=5y
y=(x+5)/5
so we have
m^-1(x)=(x+5)/5

6-7(x+1)= -3(2-x)<br> How do you solve this?
kicyunya [14]
<h3><u>Explanation</u></h3>
  • Given the equation.

6 - 7(x + 1) =  - 3(2 - x)

  • Distribute/Simplify

6 - 7x - 7 =  - 6 + 3x \\  - 1 - 7x =  - 6 + 3x

  • Solve the equation for x-term by making x as the subject.

- 1 + 6 = 7x + 3x \\ 5 = 10x \\  \frac{5}{10}  = x \\  \frac{1}{2}  = x

  • Answer Check by substituting the value of x in the equation.

6 - 7( \frac{1}{2} ) - 7 =  - 6 + 3( \frac{1}{2} ) \\ 6 -  \frac{7}{2}  - 7 =  - 6 +  \frac{3}{2}  \Longrightarrow \sf{You \:  \: can \:  \: change \:  \: sides \:   \: to \:  \: make \:  \: it \:  \: easier} \\ 6 - 7 + 6 =  \frac{7}{2}  +  \frac{3}{2}  \\ 5 =  \frac{10}{2}  \\ 5 = 5 \:  \green{ \checkmark}

The equation is true for x = 1/2.

<h3><u>Answer</u></h3>

<u>\large \boxed{x =  \frac{1}{2} }  \:  \:  \:  \: \green{ \checkmark}</u>
