Question

a) x – 3(x – 2) = 6x – 2 b) 3x – 7 = 2(x + 1) c) 2(2 + 4x) = 3 + 12x
d) 5x = 7(5x – 3) + 3 e) 2(x – 5) = 3x – 17 f) 2 + 5(x – 13)= x – 3
g) 2x – 1 = 3(2x – 15) h) 2(x – 2)= –(4 – x) i) 2(3x – 49)= –x + 14
j) 20 = 2x – (10 – 4x) k) 60x – 1 = 3(1 + 12x) l) 5(x – 1) + 10(x + 2) = 45
m) 2x + 3(2x – 1) = x + 67 n) 12x + 3(2x – 4) = 60 ñ) 3x – (x + 1) = x – 2
o) x – 3(x + 5) = 3x + 10 p) (x – 15) = 3(x – 19) q) 3(2 - x) = 18x – 1
r) 3(x + 4) = 4x + 1 s) 10 + 5(x – 3) = 3(x + 1) t) 2(3 – 4x) = 2x – 9
u) 10 - 9x = 4[x – 4] v) 15x = 2[1 + 9x] – 3 w) 3[10 – x] = 2[8 – x] + 13x
x) x + 3 = 3[2x – 4] y) 3[2x – (3x + 1)] = x + 1 z) 6x + 4 = 4[2x – 5(x – 2)]

Answer 1

Answer 2

Respuesta:

p=(2x^2+5)+(2x^2+5)+(x+2)+(x+2)=2(2x^2+5)+2(x+2)=4x^2+10+2x+4=4x^2+14+2x
