4x+9 = 7x+3
4x-7x = 3-9
-3x = -6
x = 2
7x = 3x - 12 4x=-12 x=-3
13x
4x+5=7x-8 the ansewr is 3.25
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
7x = 20 + 4xSubtract 4x from each side of the equation:3x = 20Divide each side by 3 :x = 20/3
3x + 4x = 847x = 84divide both sides by 7x = 12
4x - 7 = 5 + 7x x = -4
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
-21-4x=9-7x 7x-4x=9+21 3x=30 x=30 / 3 therefore x=10
No, that's not correct.-3x + 4x = x
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
