Question

Solve the system.
5(x-1)=29-3(y+2)
4(x+2)-22=3(2-y)
(x,y) = ( , )
Suppose to use the elimination or substitution method but i cant figure it out please help thx

Answer 1

you'll find its easier if you rearranged the equations into the form
ax + by = c

Answer 2

5x-5=29-3y+6
5x+3y=40
Right?

Answer 3

nearly
its - 6 n first line

Answer 4

4x+8-22=6-3y
4x+3y=20

Answer 5

it comes to

5x + 3y = 28

Answer 6

ok so
5x+3y=28
4x+3y=20

Answer 7

right
elimination method is quite easy
just subtract and you;ve eliminated y

Answer 8

5x+3y=28
-4x-3y=-20
-4x=8
x=-2?

Answer 9

y=-4?

Answer 10

- and got x straight away

Answer 11

What?

Answer 12

whys multiply by -1?
you've got 3y in each equation
3y-3y = 0

Answer 13

so x=8?

Answer 14

yes simple

Answer 15

now plug x=8 into any of the equations to get y

Answer 16

y=4

Answer 17

no try again

Answer 18

wrong sign

Answer 19

-4

Answer 20

4(8) + 3y = 20
3y = 20-32 = -12 y = -4

Answer 21

thx :DDDDD
