2x -6 = 4 then 2x = 4 +6 x=10/2 = 5
2x - 6 = 4 2x = 4 + 6 = 10 x = 10/2 = 5 ∴ x = 5
5
6 + 2x = x - 6 2x - x = -6 -6 x = -12
2x-6=4 6+4=2x 10=2x 10/2=x 5=x x=5
The output or y-value when you input x-4 into the function y = 2x + 6 is 2(x-4) + 6 = 2x - 8 + 6 = 2x - 2.
x+4=2x+6 x=2x+2 (subtract 4 from each side)-x=2 (subtract 2x from each side)x=-2 (multiply each side by -1)------Check-------2+4=-4+6 (Plug x value into original equation)2=2 (simplify)
2x + 4 = 6/x - 3 ∴2x - 6/x + 7 = 0 ∴2x2 + 7x - 6 = 0 X ∈ {0.71221447, -4.2122145}
2x - 6 = 4 First you must add 6 to both sides of the equation so you will get 2x = 10 Next, you will divide both sides of the equation by 2 and you will get x = 5. Finally, you may check your answer by substituting 5 in for x in the original equation: 2x - 6 = 4 2(5) - 6 = 4 10 - 6 = 4 4 = 4 Since this is a true statement, you have verified that the answer is 5 for x.
2x + 4 = y ...............2x + 4 = y ....................2x + 4 = y .............2*(-6)+ 4 = y x - y = 2 .......<=> ...x - 2x - 4 = 2 .....<=> ...x = -6......... <=>.... x = -6 ..............<=> y = - 8 x = - 6
# ## 2x > -6 and x - 4 < 3 ## x + 3 > 2x + 1 and -4x < -8 ## -6 < x + 3 < 6 ## -3x > -6 or x - 5 < 2 ## x - 2 > 2x + 1 or 10 > -2x + 2
