Question

o) 2(x + 5 ) – 4 = 26

p) 3(x + 3 ) – 5 = 22

q) 2(2x + 7 ) + 3(3x – 5 ) = 3(4x – 5 ) – 1

r) 3( x + 2 ) = 2 ( x – 7)

s) 4(2x –1 ) = 3( x+2 )

t) 4(2m-1) + 3m = 2(4m-1) – (2 –m)

u) 3(x + 3 ) - 1 = 2

v) 3(x + 1 ) + 2 = 5 + 2(x - 1 )

x) 3(2x – 3 ) + x = 5

y)3x + 5 + 2x + 6= x + 27

z) 2 ( x – 1 ) + 3(x + 1 ) = 4(x + 2)
tenho até as 23h00 me ajuda pfvvv​
