Hey sir wen changing da sign on 3 frm positive to negative are we only suppose to change on da middle number & leave other numbers da way dey are?

[@koketsolorraine3626]

You only change the signs of the coefficient

Why 7 Is positive when it comes out side

[@henrydanzooffical03361]

But why a you adding on 7 I don't know

[@NgushiMinganja-hm7jc]

Am kindly asking to add me in the group for pure subjects

[@JacklinAmponsah]

Hi sir please you negated the 3 but made the 7 positive

[@kavyakunibilli]

Here's the answer in determine we usually have signs (+ - + ) like this same as remaining also so 3 is negative signed
