Question

For the following system, use the second equation to make a substitution for y in the first equation.

3x + y = 2
y + 4 = 3x
answers
3x + 3x - 4 = 2
3x + 3 - 4x = 2
3x + 3x + 4 = 2

Answer 1

so than y+4=3x --- y=3x-4 and now substitute this value of y in first equation
3x +3x -4 =2

Answer 2

can you continue ?

Answer 3

do you need to solve this system ?

Answer 4

no?

Answer 5

so 6x=6 --- x=6/6 --- x=1
y=3x-4 so y=3*1-4 so y=3-4 so y=-1

Answer 6

i dont understand

Answer 7

What work have you done?

Answer 8

ok so indifferent but your first answer is right sure

ok ?

Answer 9

ok
