6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
x=7
9x-5x=4x, 7/4=1.75, x=1.75
5x-19 = 16 5x = 16+19 5x = 35 x = 7
7
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
If 5x + 8 = -7 then x = -3 ! -3 x 5 = -15 -15 + 8 = -7 !
5x+y=-7 3x+y=15 8=D
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
If you ask a similar question in the future, please write out the word plus if that is what you meant when you typed in the space between the X and the 11. Assuming you mean 5X +11 minus 2X equals seven, then 3X equals 18, so x= six
7-5x=10-(6x+7) 7-5x=-60x-70 +5x +5x 7=-55x-70 +70 +70 77=-55x Divide -55 -1.4 = x
5x - 7y = 5 (subtract both sides by 5x) -7y = -5x + 5 (divide both sides by -7) y = (5x - 5)/7 If you want to solve for y = 0, then x = 1.
