mk đang cần gấp , ai làm được mình sẽ tik
mong các bạn giúp đỡ
Tìm x nguyên, biết
a) -5.(-x + 7) - 3.(-x - 5) = -4.(12 - x ) + 48
b) -2.(15 - 3x) - 4.(-7x + 8) = -5 - 9.(-2x + 1)
c) 7.(-x - 7) - 5.(-x - 3) = 12.(3 - x)
d) 5.(-3x - 7) - 4.(-2x - 11) = 7.(4x + 10) + 9
e)-2.(x+3)-15=3.(4+2x)+7
Tìm số nguyên x ,biết:
a,-5.(-x+7)-3.(x-5)=-4.(12-x)+48 c,7.(-x-7)-5.(-x-3)=12.(3-x)
b,-2.(15-3x)-4.(-7x+8)=-5-9.(-2x+1) d,5.(-3x-7)-4.(-2x-11)=7.(4x+10)+9
