-46 = 3x + 7x

x=6 hope this helps

3+3x+7x=13 3x+7x=10 10x=10 x=1

7x + 16 = 3x + 4 4x = -12 x = -3

3x + 4x = 847x = 84divide both sides by 7x = 12

7x = 3x - 12 4x=-12 x=-3

x=6

7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4

simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2

x=-4.6

No, that's not correct.-3x + 4x = x

7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
