How to graph 6x + 3y = 12
explanation:

Step 1: Find x intercept: substitute 0 for y: solve for x

• 6x + 3(0) = 12
• 6x = 12
• x = 2

Step 2: Then Find y intercept: also substitute 0 for x; solve for y

• 6(0) + 3y = 12
• 3y = 12
• y = 4

So plot x and y intercepts: ( 2,0 ) and ( 0,4 ) then draw a line through the points.

How to graph 3x + y = 5
explanation:

Step 1: Find x intercept: substitute 0 for y: solve for x

• 3x + 5(0) = 15
• 3x = 15
• x = 5

Step 2: Then Find y intercept: also substitute 0 for x; solve for y

• 3(0) + 5y = 15
• 5y = 15
• y = 3

plot x and y intercepts: (5,0 ) and ( 0,3) then draw a line through the points.

Hope this help:))

The sum of three numbers is 104. The first number is 10 less than the second. The third number is 4 times the second. What are t

Shalnov [3]

Answer:

The numbers are 9, 19 and 76.

Step-by-step explanation:

Let's take the second number and make it a variable, like x. Now let's find all the other numbers in terms of x.

The first number in terms of x:

$x - 10$

The second number in terms of x:

$4x$

If we add them all up, these 3 numbers in terms of x must be equal to 104, so:

$x + (x - 10) + (4x) = 104 \\ x + x - 10 + 4x = 104 \\ 6x - 10 = 104 \\ 6x = 114 \\ x = 19$

Now that we know the second number, we can find the other numbers since we already figured out their values in terms of x:

$19 - 10 = 9$

$4 \times 19 = 76$

The first number is 9, second number 19 and the third number 76.
