Answer:
X= 3 and y=-9
Step-by-step explanation:
let
x+y=-6 be the equation..1
and 4x + y = 3 be the equation..2
now solving the two equations simultaneously using substitution method
- make x the subject in equation 1. thus the equation turns to x=-6-y when you make x the subject
- substitute x= -6-y into equation 2. Thus the equation 2 then becomes 4(-6-y)+y=3
- simplifying it.. -24-4y+y=3 furthermore ,-24-3y =3 .
solving for y in the relation (-24-3y)=3 . group like terms hence the equation changes to -24-3=3y
-27=3y. divide through by 3
as -27/3=3y/3 to obtain
-9=y.
therefore the value for y is -9
put the y value in either of the two equations to obtain x value
substituting it into equation 1
where x+y =-6
put the y value at the position of y to obtain x-9=-6
x=-6+9
x=3
therefore the value for x and y are 3 and -9 respectively.
Answer:
you must solve the question.
Step-by-step explanation:
it would be when we're solving a formula for himself a variable we must solve it.
Answer:
x = -30/7
Step-by-step explanation:
-7x+3y=30
Let y=0
-7x +0 = 30
Divide by -7
-7x /-7 = 30/-7
x = -30/7
Answer:
Like Terms: and .
Coefficients: and .
Constant:
Step-by-step explanation:
"Like terms" are terms whose variables (and their exponents such as the in ) are the same. In other words, terms that are "like" each other.Example: , , and are like terms because they all have .
Coefficients are a number used to multiply a variable. In the above example, the coefficients would be , , and . In your problem, they're and .
Constants are numbers not attached to variables. See the diagram attached.
