Question

Simplify 6 - 4[x + 1 - (y + 3)] + 5y

Answer 1

-4x+8y+14

Step-by-step explanation:

Using P.E.M.D.A.S- you would first do the brackets [...] as y+3 cannot be simplified

6-4[x-y-2]+5y

Then distribute -4 into the brackets [...] - think of brackets as parenthesis

-4x+4y+8=-4[x-y-2]

so,

6-4x+4y+8+5y

then,

-4x+8y+14
