Question

2[7(2x-1)-3(4X-3)]-12 =5[1-2(2-3x)]-14​

Answer 1

Răspuns:

2[7(2x-1)-3(4x-3)]-12=5[1-2(2-3x)]-14

2(14x-7-12x+9)-12=5(1-4+6x)-14

2(2x+2)=5(-3+6x)-14

4x+4=-15+30x-14

4x+4=-29+30x

4x-30x=-29-4

-26x=-33

26x=33

x=33/26

Explicație pas cu pas:

Answer 2

2(14x-7-12x+9)-12=5(1-4+6x)-14
2(2x+2)-12=5(-3+6x)-14
4x+4=-15+6x-14
4x-6x=-29-4
-2x=-33|*(-1)
2x=33
X=33/2
