You do not need any steps to solve X = 6! The solution is already given!!!X equals 6.
x = 20
First you put -6 under 6 so they cancel each other out. The do 7 - 6 which equals 1. So x equals 1
7x=42 x=42/7 or, x=6
5/6=x/30 150=6x 25=x
-x=-2
The equation 6 x-1 18x can be simplified to the answer 112x.
x = -4/3
x=4 and x =7Improved Answer:-x2-18x-40 = (x+2)(x-20) when factored
x² - 18x - 4 = o x² - 18x = 4 x² - 18x + (18/2)² = 4 + (18/2)² x² - 18x + 81 = 4 + 81 (x - 9)² = 85 x - 9 = ±√85 x = 9 ±√85 x = 9 + √85 or x = 9 - √85 if you are still confused, i want you to follow the related link that explains the concept of completing the square clearly.
18x= 19818x/18 = 198/18x = 11
x = -2/3,7/6
X is 6
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
x=6
18x + 12y = 72 to get x-int. put y=0 18x + (12)(0) = 72 18x = 72 x = 4 your x-intercept is 4. this is the place where the line goes through the x-axis.
