How can I solve this system of linear equations by substitution 2x-3y=-24 and x+6y=18

Answers

Answer 1

Answer: to sub
solve for 1 variable
solve for x
minus 6y both sides on second equotn

x=18-6y

sub 18-6y for x in other equation
2(18-6y)-3y=-24
36-12y-3y=-24
36-15y=-24
minus 36 oth sides
-15y=-60
divide -15 both sides
y=4

sub back

x=18-6y
x=18-4(4)
x=18-16
x=2

x=2
y=4
(2,4)

How do you now 11/33 is a simplest form

Answers

it is not the simplest form. the simplest form would be 1/3. this is because with such a fraction as 11/33, you have a common factor with them, which is 11. reduce the fraction until there are no common multiples for the numerator and demonimator.

33=11+11+11 so 11/33=11/(11+11+11) represent a third part of an integer
so 11/33=11/(3x11)=(11/11)x(1/3)=1/3=0,(3) can be simplified by 11, so its not simple form as 1/3 is
