Resolver las ecuaciones

a) 6x – (4x – 7) = 5x – (4 – 9x) + (-4x + 35)

b) 9x + (-2x + = 3x + (5 – 6x) – (-5x – 18)

c) 4x – (3x – 10) = 2x – (8 – 5x) + (3x – 18)

d) 3x + {-7x + (-x + 9)} = 33 – { – (3x + 2) – (3x – 14)}

e) 4x – {-5x – (-3x + 10)} = 18 +{ -(5x + 4) + (-7x + 12)}

f) 9x + {-6x + (-2x + 9)} = -5 – { -(7x + 3) – (-9x + 22)}

g) 3(2x – 4) – 4(5 – 2x) = 3(x – 2) + 5(4x + x) + 2

h) 4(x – 2) + 3(x + 5) = 2(x + 2) – 3(x – 4) + 17

i) 3(x – 2) – 6(3 – 2x) = 3(5x – 2) + 3(2x – x)

j) 10x – (8x – 5) = 7x –(5 – 9x) + (-3x – 45)

k) 3x – (5x + = 4x –(6 – 2x) – (-4x + 26)

l) 9x + {-7x + (-x + 25)} = 12 – {-(3x + 2) – (3x – 4)}

m) –5x – {-x –(-2x + 5)} = -8 – {-(4x + – (2x + 3)}

n) 6(x + 3) + 2(x – 5) = 4(x – 3) + 3(x + 7)
