Which number line represents the solution 6x < 42 ?

first one it is {all -,7}

C, or the 3rd one down

Step-by-step explanation:

this is because, 6x < 42. this means rhe 6x is less then 42. meaning that the ling would have to be facing towards the left. and as well as having an open circle to represent that the number line presents a "less than or equal to" equation.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
