-7x + 5 = -9 -7x = -14 7x = 14 x = 2
23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2
7x is still the slope, no matter what x equals.
4x+5=7x-8 the ansewr is 3.25
-9-7x=-5 express first the equation in terms of x, where, 7x=-9+5 then, 7x=-4 thus, x=-4/7
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
11X - 23 = 7X + 5 subtract 7X from both sides 11X - 7X - 23 = 7X - 7X + 5 4X - 23 = 5 add 23 to both sides 4X - 23 + 23 = 5 + 23 4X = 28 divide both sides integers by 4 (4/4)X = 28/4 X = 7 --------------------check in original equation 11(7) - 23 = 7(7) + 5 77 - 23 = 49 + 5 54 = 54 checks
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
If x=2, then 7x = 14 and if y=5 then 4y=20.
23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2
X = 10 7x-5=65 +5 +5 7x=70 /7 /7 So X=10
7x is still the slope, no matter what x equals.
4x+5=7x-8 the ansewr is 3.25
-9-7x=-5 express first the equation in terms of x, where, 7x=-9+5 then, 7x=-4 thus, x=-4/7
Let x be the varible: 7x-5 = 37 7x = 37+5 7x = 42 x = 6
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
7x+5-14 = 28 7x = 28+14-5 7x = 37 x = 37/7 = 5.'285714' recurring
