Question

resolva as equações(se puder clcr a conta agradeço)
a, 3-(3x-6)=2x + (4-X)
b. 4(x-2) = 4+2 (x - 1)
c.7x-3 (x-2) = 3 (x+4)
d. 2 (x-2) + 5 (2-1) = -3 (2x+2) ​

Answer 1

Resposta:

A) 3 - (3x - 6) = 2x + (4 - x)

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

9 - 3x = x + 4

9 - 4 = x + 3x

4x = 5

x = 5/4

B) 4 (x-2) = 4 + 2(x-1)

4x - 8 = 4 +2x -2

2x = 10

x = 5

C) 7x-3.(x-2)=3.(x+4)

7x-3x+6=3x+12

7x-3x-3x=12-6

7x-6x=6

x=6

D)  2(x-2) +5x (2-1) = -3(2x+2)

2x4+105=-6x-6

2x + 6x = −6+4-10+5

8x 6+4 -10 + 5

8x = -7

X = -7÷8

x = -0.875
