Question

A) 4x+6=2x×18 B)2(x+1)-3(2x-5)=6x-3 C ) 3(x-2)=4 (-x+3 ) D ) 4 (x+5)+3(x+5) =21

Answer 1

B ) 2(x+1) -3(2x-5) = 6x-32x+2-6x+15=6x-3
2x-6x-6x=-3-2-15
-10x=-20
x=-20/-10
x=2

C) 3(x-2)=4(3-x) 
3x-6=12-4x 
3x+4x=12+6 
7x=18 
x=18/7

D)
4(x+5)+3(x+5)=21 
4x+20+3x+15=21 
7x+35=21 
7x=21-35 
7x= -14 
x= -14/7 
x= -2
