Question

Помогите Решить(срочно):
1) 5х+(3у-12х)=..
2)-(-3у-5х)-(8х+4)=..
3)(9-4у)+(-4у-16)=..
4)-(-5у-10)-(3у+5)-(-8+9у)=..
5)3(7х-5)-4(9-6х)+4=..

Answer 1

1) 5х+(3у-12х)=5x+3y-12x=-7x+3y
2)-(-3у-5х)-(8х+4)=3y+5x-8x-4=3y-3x-4
3)(9-4у)+(-4у-16)=9-4y-4y-16=-8y-7
4)-(-5у-10)-(3у+5)-(-8+9у)=5y+10-3y-5+8-9y=-7y+18
5)3(7х-5)-4(9-6х)+4=21x-15-36+24x+4=45x-47

Спасибо :)

Answer 2

1)5x+(3y-12x)=5x+3y-12x=-7x+3y
2)-(-3y-5x)-(8x+4)=3y+5x-8x-4=3y-3x-4
3)(9-4)+(-4y-16)=9-4y-4y-16=-7-8y
4)-(-5у-10)-(3у+5)-(-8+9у)=5y+10-3y-5+8-9y=-7y+13
5)3(7х-5)-4(9-6х)+4=21x-15-36+24x+4=45x-47
