4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
6x-7 = 4x+23 (take the x terms on one side and the number terms on the other) 6x -4x = 23 + 7 therefore 2x = 30 x=30/2 x=15
what is the product of ( 4x-7) (4x+7)
If 6x-7=35 then 6x=35+7=42 and x=7
7+10+(-6x)=17-6x
-6x + 5 = -4x + 19add 6x to both sides5 = 2x + 19subtract 19 from both sides-14 = 2xdivide both sides by 2-7 = x
4x-1 = 6x-15 4x-6x = 1-15 -2x = -14 x = 7
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10
6x-7 = 4x+23 (take the x terms on one side and the number terms on the other) 6x -4x = 23 + 7 therefore 2x = 30 x=30/2 x=15
10x + 7 = 4x + 49 6x + 7 = 49 6x = 42 x = 6
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
4x(4x^2 - 6x + 7)
6x - 7 = 2x + 13Subtract 2x from each side ==> 4x - 7 = 13Add 7 to each side ==> 4x = 20Divide each side by 4 ==> x = 5
8x2+6x-35 = (2x+5)(4x-7) when factored
2x + 5 = 7 - 4x ie 2x + 4x = 7 - 5 ie 6x = 2 x = one third.
