3
What is X - Y equals 6 and -3y equals X plus 22?
x-y = 6 -x-3y = 22 -4y = 28 y = -7 So by substituting: x = -1 and y = -7
15 plus 14 plus 14 plus 11 plus 2x plus x equals 75?
15 + 14 + 14 + 11 + 2x + x = 75 Collect like terms 54 + 3x = 75 Subtract 54 3x = 21 Divide by 3 x = 7 ■
X plus y equals 7 and x plus 2y equals 11?
x=3 and y=4. you multiply x+y=7 by neg. 2 this way you can cancel out the y factors and get neg. 2x+x=-14+11 neg. x = neg. 3 divide both sides by neg. 1 to get x=3. use substitution to get y=4
How do you solve y equals 7 plus x?
y=7+x =x=7-x
2x plus 22 equals 13x minus 7?
x=-(29/11)
Find the solution of x-7 plus 7 equals 11 plus 7?
x-7+7=11+7 x=11+7 x=18
What is -8 x -11 plus -22?
-8 x -11 + (-22) = 88 - 22 = 66
How do you solve x2 plus 13x plus 22?
11+2 = 13 and 2*11 = 22 So: x2+13x+22 = (x+2)(x+11) when factored
What is (-2x 4) plus (x-11)?
-8 x -11 + (-22) = 88 - 22 = 66
What is the prime for 21 22 and why?
3 x 7 = 21 2 x 11 = 22 because 3 x 7 = 21 2 x 11 = 22
What is X over 11 plus 21 equals 7?
x/11 + 21 = 7 x/11 = -14 x = -154
Is X over 11 plus 21 equals 7?
x/11 + 21 = 7 x/11 = -14 x = -154
What is the LCM of 308 and 252 and198?
2772. 308 = 22 x 7 x 11 252 = 22 x 32 x 7 198 = 2 x 32 x 11 lcm = 22 x 32 x 7 x 11 = 2772
How to Solve the system using substitution 3x plus 2y equals 7 y equals negative 3x plus 11?
Where is y in the first equation, you put its equivalent (=) -3x + 11 The first equation is then transformed into: 3x + 2*(-3x + 11) = 7. Then you get: 3x + (-6x) + 2*11 = 7 <=> -3x + 22 = 7 <=> 22 - 7 = 3x <=> 3x = 15 <=> x = 15/3 <=> x = 5. Then you substitute the x in the second equation by its equivalent so, (x = 5) y = -3*x + 11 <=> y = -3*5 + 11 <=> y = -15 + 11 <=> y = -4. x = 5. y = -4.
How do you write 22 over 77 in simplest form?
22/77 in simplest form is 2/7, because 22/77 = 2 x 11 / 7 x 11 = 2/7
