Question

galera me ajudem por favor
1) resolva as equações do 1 grau.

A) y-3=-4y+7

B)– x – 2x – 4 = 11 – 2x + 4x

c) 9 – x + 2 = - 5x + 37

d) 4x – 3 – 2x = - 20 – 3 – 2x

e) 3(x + 10) – 2(x – 5) = 4 – 5×

f) 2(x – 6) = - 3(5 + x)

g) 3(x – 1) – 2(x – 4) = 1

h) 9y – (4 – 9y) = - 12

i) 7(x – 1) – 2(x – 5) = x - 5

j)
\frac{3x}{4} - \frac{x}{2} = - 243x​−2x​=−2
k)
\frac{x}{3} + \frac{x}{2} = - 23x​+2x​=−2
l)
\frac{3x}{9} - 2 + \frac{2x}{3}93x​−2+32x​
m) 2(y-3)+4=-2y+6

n) 10-2(3x+1)=5+3(x-5)
​

Answer 1

Resposta:

a) 5y = 10

y = 2

b) -5x = 15

x = -3

c) 4x = 26

x = 13/2

d) 4x = -20

x = -5

e) 6x = -36

x = -6

f) 5x = -3

x = -3/5

g) x = -4

h) 18y = -8

y = -4/9

i) 4x = -8

x = -2
