Just add them together. For example if you have 4x and 7x you would just do 4x+7x and get 11x. You can only add them because they are like terms, meaning that they share a variable.

Answer:
y = -
x - 11
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 10, - 7) and (x₂, y₂ ) = (- 5, - 9)
m =
= -
, hence
y = -
x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 5, - 9 ), then
- 9 = 2 + c ⇒ c = - 9 - 2 = - 11
y = -
x - 11 ← in slope-intercept form
X = 8
y = 6
a = 10
? = 1920
x + y + x = 22
8 + 6 + 8 = 22
a + a + x = 28
10 + 10 + 8 = 28
y + 2y + 2a = 38
6 + 2(6) + 2(10) = 38
2y * x * 2a =
2(6) * 8 * 2(10) = 1920
Answer:
One of the number is 4 while the other is 7
Step-by-step explanation:
The sum of two numbers is eleven
Let the numbers be x and y
X+ y = 11
One number is thirty-eight less than six times the other
X= 6y-38
X+ y = 11
6y-38 +y= 11
6y+y= 11+38
7y=49
Y= 49/7
Y= 7
X+ y = 11
X+7= 11
X= 11-7
X= 4
