# How do you solve the system of linear equations by elimination 12x-7y=-2, 8x+11y=30?
Jun 8, 2018
$x = 1$
$y = 2$
#### Explanation:
Solving By Elimination
$12 x - 7 y = - 2$
$8 x + 11 y = 30$
First, let's have a look at our system and recall what the elimination method is. To eliminate a variable (either $x$ or ... |

Students Arn, Bob, Cyd, Dan, Eve, and Fon are arranged in that order in a circle. They start counting: Arn first, then Bob, and so forth. When the number contains a 7 as a digit (such as 47) or is a multiple of 7 that person leaves the cir... |
## How Do You Find The Equation Of A Tangent Line?
A tangent line to a function is a line that looks most like the function at a point. In common terms, it just grazes the function.
To find its equation, we need to locate the point where the two meet as well as the slope of the function at that point. Then we can use... |

# xplusa into xplus b
x plus a into x plus b Formula :
In this section, we are going to see the formula/expansion for (x + a)(x + b).
That is,
(x + a)(x + b) = x2 + xb + xa + ab
(x + a)(x + b) = x2 + (b + a)x + ab
(x + a)(x + b) = x2 + (a + b)x + ab
