Question

me ajudeeeem p) (x + 3) - X = 24 + x
q) (x + 5) - 3( 5 – *) = 5
r) 4 (x + 3) = 4
5) 6 (2x - 3) = 6
t) 5 (2x - 4) = 7 (x+1) - 3
u) 7 (x - 5) = 3 (x-1)
v) 3 (x - 2) = 2x - 4​

Answer 1

p)

$(x + 3) - x = 24 + x \\ - x = 21( - 1) \\ x = 21$

q)n entendi

r)

$4(x + 3) = 4 \\ 4x + 12 = 4 \\ 4x = - 8$

s)

$6(2x - 3) = 6 \\ 12x - 18 = 6 \\ 12x = 24 \\ x = \frac{24}{12} \\ x = 2$

t)

$5(2x - 4) = 7(x + 1) - 3 \\ 10x - 20 = 7x + 7 - 3 \\ 3x = 24 \\ x = \frac{24}{3} \\ x = 8$

u)

$7(x - 5) = 3(x - 1) \\ 7x - 35 = 3x - 3 \\ 4x = 32 \\ x = \frac{32}{4} \\ x = 8$

v)

$3(x - 2) = 2x - 4 \\ 3x - 6 = 2x - 4 \\ x = 2$
