5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
5x - 4 = -4add 4 to both sides5x = 0x must equal 0.
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
7x-5x=8 2x=8 x=4
5x+c
Yes.
2+2=4
I don't know what a 'mathematical' sentence is. I'd prefer to call it an English sentence that describes a mathematical process and makes a statement concerning mathematical matters.
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
The problem should read: 3x^2 (5x-4) - 5 (5x-4)
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6
The answer to the math problem of 5x plus 12 equals 93-4 is 77/5.
9x-5x-2x = -4 2x = -4 x = -2
5x - 4 = -4add 4 to both sides5x = 0x must equal 0.
