Question

5 Resolva Cada equação
a)3x+2=2x-11
b)25(3x-2)=12x+6​

Answer 1

a) 3x+2 = 2x-11

3x-2x = -11-2

x = -13.

b)25(3x-2) = 12x+6

75x-50 = 12x+6

75x-12x = 6+50

63x = 56

x = 56/63.

Answer 2

Oi...

a)

3x + 2 = 2x - 11

3x - 2x = - 11 - 2

x = - 13

b)

25(3x - 2) = 12x + 6

75x - 50 = 12x + 6

75x - 12x = 6 + 50

63x =  56

x = 56/63 ÷ 7

x = 8/9​

Bons estudos.
