Question

can you help me solve each equation system by the addition method?
4x+2y=6
4x-5y=-1
thank you. xx

Answer 1

hint: multiply 2nd equation by -1

Answer 2

either 1st or 2nd
multiply one of equation by -1

Answer 3

4x+2y=6
4x-5y=-1
Can we add the two and get rid of 4x? @Nnesha

Answer 4

so then would it be 8x instead of just 4x?

Answer 5

i think we can just add them and get off 4x

Answer 6

that leaves us with
7y = 7

Answer 7

both 4x are positive

Answer 8

the other one will become -4x though

Answer 9

@satellite73 i am right or wrong?

Answer 10

i mean like
4x + 2y = 6
4x - 5y = -1
so on adding it will be
-4x _ 5y = 1

Answer 11

-4x + 5y = 1 sorry

Answer 12

so
4x + 2y = 6
-4x +5y = 1
that gives
7y = 7

Answer 13

@KenichiIvy yes that's why i said to multiply by -1

Answer 14

So i am also correct @Nnesha ?

Answer 15

7y = 7
so y = 7/7
y = 1
