x2+12x+36=0 2x+12x+36=0 14x+36=0 14x=-36 x=-36/14 x=-2 4/7
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
It is: 12x
17
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
This is not an inequality. This is an equation.12x+7=43 12x=36 x=3
12x - 8 = 10x + 42x = 12x = 6
y = 12x + 5x - 7 Since '12x' and '5x' both have the same variable, you are able to combine them. To do this you just need to add 12 + 5 to get 17. After doing this you can rewrite the equation as y = 17x - 7. You can then solve this equation for different values by plugging in a number for 'x' or 'y' or graphing the equation.
An equation where x = 3
-7+x=13x the -7=12x and x =-7/12
6x+7 = -56x = -12x = -2
-5 + 12x = 18x + 7Subtract 7 from each side:-12 + 12x = 18xSubtract 12x from each side:-12 = 6xDivide each side by 6:-2 = x
The answer is 4 because you multiply both 48 and 12 by the variable (and considering the variable is x) it would equal: 48=12x then you divide both ides by 12 it would equal 4=x the variable equals 4
12x + 17 = 7 Subtract 17 from both sides: 12x = -10 Divide both sides by 12: x = -10/12 = -5/6
7
52 + 12x + 7 = 0 This is called a linear equation with one unknown (or one variable). To solve it perform mathematical operations (addition, subtraction, multiplication, division) but whatever you do to one side of the equation, you must also do to the other side. Try to place the terms involving "x" on the left hand side and the remaining terms on the right hand side. Subtract 52 from both sides. 52 - 52 + 12x + 7 = -52 : 12x + 7 = -52 Subtract 7 from both sides, 12x + 7 - 7 = -52 -7 : 12x = -59 If appropriate, divide both sides by 12 12x/12 = -59/12 : x = -59/12 If required, the answer could be converted into a decimal number : x = -59/12 = -4.917 (3dp)
The y intercept is 7/3 and the slope is -4
