When solving equations that have only one type of variable, you just get the variable on one side and the numbers on the opposite side.

6x + 7 = 8x - 13

Let us get the x on the left side.

Subtract each side of the equation by 8x.

6x + 7 = 8x - 13

-2x + 7 = -13

Subtract 7 from each side of the equation.

-2x = -20

Divide both sides by the coefficient of x. Which is -2.

x = 10

So, x is equal to 10 for this equation.

Tickets for the school play sell for S4 each. Which graph shows the relationship between the number of tickets sold

Fiesta28 [93]

Answer:

Step-by-step explanation:

Tickets for the school play sell for $4 each.

Number of tickers sold = x

Total income from the tickets = y

This means when x = 1, y = 4

SO when we sell 1 ticket (x = 1), we make $4 income (y = 4).

If we sell 2 tickets (x = 2), we will make $8 income (y = 8)

If we sell 3 tickets ( x = 3) , we will make $12 income (y = 12)

If we sell 4 tickets ( x = 4), we will make $16 income ( y = 16) etc.

Also note that when we sell 0 tickets (x = 0), we make no income (y = 0).

So if you create a graph, it should look something like this:
