X^2-5x=12
2x^2-5x-12=0
2*-12=-24; The two factors of -24 whose sum is -5 are -8 and +3.
2x^2+3x-8x-12=0
x(2x+3)-4(2x+3)=0
(x-4)(2x+3)=0
x=4,
2x=-3, x=-3/2
.
Answer:Angle MNO=105°
x=21°
Step-by-step explanation:Angle MNO+Angle TUV=180°
75+5x=180°
5x=105°
x=21°
Angle MNO=105°
The value of the variable x will be 7 that holds true for the equation.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
A number is 5 more than 3 times another number.
The sum of the two numbers is 33.
Let the number be x.
Then the another number will be 3x + 5.
Then the equation will be
x + 3x + 5 = 33
Then the value of x will be
4x + 5 = 33
4x = 28
x = 7
Then the value of the variable x will be 7 that holds true for the equation.
