If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
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
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
4x-y+7=0
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
It is a mathematical equation, usually written like this: 5x - 7 + 2x = 3x - 2 + 4x
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
x=3 That wasn't hard at all. 5x-10=-7+4x -4x -4x _____________ x-10=-7 +10 +10 _____________ x=3
Add 4x - 2 to each side: 5x = 5 x = 1
-4x +5x +4 =7 x + 4 = 7 x = 3
9x-5x=4x, 7/4=1.75, x=1.75
4x+7=9x+7 -5x=0 x=0
x=2 5(2)+2-4(2) = 7-3 10+2-8 =4
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
-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
