8 0

Answer:

x = -7

Step-by-step explanation:

To find the value of x, you need to set up a proportion:

\frac{x-2}{15} = \frac{x-1}{18}

Then cross multiply:

15x - 15 = 18x + 36

Then subtract 15x from both sides:

-15 = 3x + 36

Subtract 36 from both sides:

-51 = 3x

Finally, divide both sides by 3:

x = -7

Y/3 - 4 = -1 solve for y
Marysya12 [62]

Answer:

y=9

Step-by-step explanation:

First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction

y/3 -4= -1

y/3= 3

Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.

y/3=3

y=9

Thus we get that the value for y is 9.

Hope this helped!

Btw you're very pretty! <3
