Question

A)6×=2×+8. B)5×-2=18+3× C) 7(×-2)=5(×+3) D)2(×-6)=-3(5+×)E)3(2×-1)=-2(×+3)F)6(×-3)-9(×-1)=5-(×+3)

Answer 1

$A)$ $6x=2x+8\\6x -2x=8\\4x=8\\x=\frac{8}{4} \\x=2$

B) $5x - 2 = 18 + 3 \\5x=18+3+2\\5x=23\\x=\frac{23}{5} \\x=4,6$

C)$7 (x-2) = 5 (x+3)\\7x - 14 = 5x + 15\\7x - 5x = 15 +14\\2x = 29\\x= 14,5$

D) $2 (x-6)= -3 (5+x) \\2x - 12=-15 - 3x\\2x + 3x = -15 + 12 \\5x = -3\\x=\frac{-3}{5}$

E) $3(2x-1)=-2(x+3)\\5x - 3 = -2x-6\\5x+2x=-6+3\\7x=-3\\x=\frac{-3}{7}$

F) $6(x-3)- 9(x-1) = 5.(x+3)\\6x - 18 - 9x +9=5.(x+3)\\-3x -9 = 5x + 15\\\\\\-3x-5x=15-9\\-8x=6 (-1)\\x= \frac{6}{8} \\x= \frac{3}{4}$
