Eighteen is fifteen less than the product of a number and three .Find the number

x = 11

Explanation:

(x · 3 - 15) = 18

[ Step 1: Simplify both sides of the equation ]

x(3) − 15 = 18

3x + −15 = 18

3x − 15 = 18

[ Step 2: Add 15 to both sides ]

3x − 15 + 15 = 18 + 15

3x = 33

[ Step 3: Divide both sides by 3 ]

3x / 3 = 33 / 3

x = 11

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
