Question

1) 2*(x+y)+3*(6y+4x)=

2) 27x-78y-(3x+6y)=

3) 8*(97x+76y)+3*(44x-67y)=

4) 7*[99x+34y-56c]=

5) 8*(x+y)+9(2x+3y)

Answer 1

Respuestas:

1) 2*(x+y)+3*(6y+4x) = 2x+2y+18y+12x = 14x+20y

2) 27x-78y-(3x+6y) = 27x-3x-78y-6y = 24x-84y

3) 8*(97x+76y)+3*(44x-67y) = 776x+608y+132x-201y = 908x+407y

4) 7*[99x+34y-56c] = 7(99x) + 7(34y) + 7(-56c) = 693x+238y-392c

5) 8*(x+y)+9(2x+3y) = 8x+8y+18x+27y = 26x+35y
