Answer:
x=1
Step-by-step explanation:
x+y=4
replace y with 3x
x+3x=4
then add the x which is 1x plus 3x
4x=4
then divide 4 on both sides
4x/4=4/4
and your answer is 1
Supposing that the first term is obtained for
=6+0\times(-2)=6[/tex]
then we obtain the sixth term by setting n = 6 in the formula like this:
Answer:
x = 0
y = -2
Step-by-step explanation:
to solve this simultaneous equation we are going to say
let
12x - 3y = 6 ............................ equation 1
2x - y = 2 ................................. equation 2
from equation 2
2x - y = 2 ................................. equation 2
2x - 2 = y
y = 2x - 2 ................................ equation 3
substitute the value of y into equation 1
12x - 3y = 6 ............................ equation 1
12x - 3( 2x -2) = 6
12x -6x + 6 = 6
6x + 6 = 6
6x = 6-6
6x = 0
divide both sides by 6
6x/6 = 0/6
x = 0
put the value of x = 0 into equation 3
y = 2x - 2 ................................ equation 3
y = 2(0) - 2
y = 0 - 2
y = -2
therefore from the solution the value of x is equal to zero(0) and the value of y is equal to -2 respectively.
