Solve the system by subsitiution

or

Step-by-step explanation:

Begin by substituting for in the first equation given:

Add to both sides of the equation:

Divide both sides of the equation by the coefficient of , which is :

Now, substitute the value into the second equation given:

Distribute the negative:

-

You can check your work by substituting the solved values into one of the given equations. Let's use the second one, as it will be easier to work with:

Since the sides of the equation are equal to each other, our solution is correct!

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
