-46 = 3x + 7x

There is only one solution: -46 = 3x + 7x -46 = 10x x = -46/10 = -4.6

Just one.-46 = 3x + 7xCombine the 'x' terms:-46 = 10xDivide each side by 10:-4.6 = x

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

8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3

1

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

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

x=6

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

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
