2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
6 2(6) + 3 = 9
2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
4x-6 = -2x-3 4x+2x = 6-3 6x = 3 x = 3/6 = 1/2
2x + 3 = 6 2x = 3 x = 3/2 = 1.5
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
if 2x+3=9 then 2x=6 so x=3
2x=6 /2=/2 x=3
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
2x+3=3x-3 2x-3x=-3-3 -x=-6 x=6
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
No but y = -1/2x+3 is perpendicular to y = 2x+6
-2(5x+3)-2x<-3(2x-4)+2
common it's very easy !!2x + 3 = 92x = 6x = 6/2x = 3
