Answer 1

Explicación paso a paso:

•2(x+3)-12=318

2x+6-12=318

2x=318-6+12

x=324/2

x=162

•4x-5=-68-3x

4x+3x=-68+5

7x=-63

x=-63/7

x=-9 (+)

•3(x+4)+2=90+3x

3x+12+2=90+3x

3x-3x=90-12-2

x=76

•-6(x-1)+10=-2x+136

-6x+6+10=-2x+136

-6x+2x=136-6-10

4x=120

x=30

•2(2x+1)+14=4x+16

4x+2+14=4x+16

4x-4x=16-14-2

x=0

•4(x+1)+2x=3(x-2)-410

4x+4+2x=3x-6-410

4x+2x-3x=-416-4

x=412
