5x + 10y = 18
x = y - 6
which of the following equations is the result of substituting y - 6 in for x in the first equation?

a)5x + 10y - 6 = 18
b)5y - 6 + 10y = 18
c)5y - 30 + 10y = 18

option (c) (5y - 30 + 10y = 18)

Step-by-step explanation:

The given equation are 5x + 10y = 18 (1)

                        and  x = y - 6 (2)

Now we have to find the equation which is the result of substituting ( y-6 ) in for x in the first equation.

By substitution in equation (1)

5 ( y-6 ) + 10y = 18

5y - 30 + 10y = 18

Therefore, option (c) (5y - 30 + 10y = 18) is the answer.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
