Ella simplifies (3b+4r)+ (-2b-r) and says the result is b+ 5r. what error did ella make?

Elsa's error was adding (4r+r) instead of subtracting (4r-r)

Step-by-step explanation:

we have

step 1

Eliminate the parenthesis

step 2

Group terms that contain the same variable

step 3

Combine like terms

therefore

Elsa's error was adding (4r+r) instead of subtracting (4r-r)

i think the answer is b.

step-by-step explanation:

not 100% sure though.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
