Question

A) 2x + 3 = x + 4



B) 4x +1 = 2x + 5


C) 5x -11 = 2x + 10

Answer 1

Explicación paso a paso:

A) 2x + 3 = x + 4

2x-x=4-3

X=1

Comprobación:

2x + 3 = x + 4

2(1)+3=1+4

2+3=5

5=5

B) 4x +1 = 2x + 5

4x-2x=5-1

2x=4

x=4/2

x=2

Comprobación:

4x +1 = 2x + 5

4(2)+1=2(2)+5

8+1=4+5

9=9

C) 5x -11 = 2x + 10

5x-2x=10+11

3x=21

x=21/3

x=7

Comprobación:

5x -11 = 2x + 10

5(7)-11=2(7)+10

35-11=14+10

24=24
