Question

Ma poate ajuta cineva?

Answer 1

e)32+6•x=11•x-113

32=11x-113-6x=5x-113

32+113=5x

145=5x

$\frac{145}{5} = x$

29=x

x=29

f)8+13•x=2•x+41

13x=2x+41-8=2x+33

13x-2x=33

11x=33

$x = \frac{33}{11} = 3$

Answer 2

a) 23+5x=2x+74

5x-2x=74-23

3x=51

x=51:3=17

b) 32+6x=11x-113

6x+11x=113+32

17x=145

x=8,52

c)8+13x=2x+41

13x-2x=41-8

11x=33

x=3
