8) X= -1

Divide both sides by 12, move the constant to the right, and subtract

9) X= 31.5

Multiply both sides by 7, reduce and multiply

10) X= 12
11) X= -12
12) y= 3/2
13) y= 2/3 I believe if the cropped out number is 6

Step-by-step explanation:

8, 12(3-x)=48

36-12x=48

-12x=48-36

-12x=12 both side divideos by -12

-12x/-12=12/-12

x= 1

9, x/7=4.5 cris cross

x=31.5

10,5(x-3)=45

5x-15=45

5x=45+15

5x=60 both side divided by 5

5x/5=60/5

x=12

11,-3(x-3)=45

-3x+3=45

-3x=45-3

-3x=42 both side divided by -3

-3x/-3=42/-3

x=14

12,14y-8=13

14y=13+8

14y=21 both side divided by 14

14y/14=21/14

y=1.5

13,3m=5m-8/5

3m-5m=-8/5

-2m=-8/5 cris cross

-10m=-8 both side divided by -10

-10m/-10=-8/-10

x=0.8

The linear equation that represent the left balance of sanjaya’s y after visiting x number of days is:

y = 10x + 500.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

From the data given, we have that:

  • The y-intercept is of 500.
  • The slope is of 10.

Hence the balance is given as follows:

y = 10x + 500.
