4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
4x-7=5x-2 x=-5
5x-4x+3=7just adding steps5x-4x+3=7you put numbers to getter but change sign5x-4x=7-35x-4x=4then it is clear5(4)-4(4)=720-16=7so as he said x=4
x=-3
4x-y+7=0
-4x +5x +4 =7 x + 4 = 7 x = 3
4x+7=9x+7 -5x=0 x=0
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
It is a mathematical equation, usually written like this: 5x - 7 + 2x = 3x - 2 + 4x
x=3 That wasn't hard at all. 5x-10=-7+4x -4x -4x _____________ x-10=-7 +10 +10 _____________ x=3
4x-7=5x-2 x=-5
9x + 7 = 5x + 35Subtract 5x from each side of the equation:4x + 7 = 35Subtract 7 from each side:4x = 28Divide each side by 4:x = 7
Add 4x - 2 to each side: 5x = 5 x = 1
5x + 7 + 4x = 79 9x + 7 = 79 (Gather the x's) 9x = 72 (Take away 7 from each side) x = 8 (Divide each side by 9 to get the answer)
4x-9(x plus 1)7-5x?
