2018年5月4日 · #y=-x+8#-----> by subtracting #x# both sides. #y-x=8# #y=x+8#----> by adding #x# both sides. Now we have: #y=-x+8# (red line graph) #y=x+8# (blue line graph) Create a …

2018年5月7日 · The solution is x=6, y=2: See explanation below. To solve such a system you should regard each equation as a function of x and y, where x_1+y_1=8, or y_1=-x_1+8 To be …

x+y=8 x-y=6 ** rewrite equations into standard form for straight lines: y=mx+b, m=slope, b=y-intercept x+y=8 x-y=6.. y=-x+8 y=x-6 equate two equations-x+8=x-6 2x=14 x=7 y=x-6=7-6=1 …

(x+y)^8 Here we have to expand the 8th power. Ninth raw in Pascal's triangle gives the coefficient of the terms in the resulting expansion. that means, the coeffients are, 1 8 28 56 70 56 28 8 1 …

x+y=8 x-y=2: solve by elimination. These are set up with no manipulation of equations. Just add the two equations together. the y terms are eliminated because +y-y=0. We are left with …

Divide both sides by to isolate y. Break up the fraction. Reduce. So the equation is now in slope intercept form where the slope is and the y-intercept is note: the y-intercept is the point If you …

You can put this solution on YOUR website! If 2x+y=8 and x-y=1,then y=. 2x+y=8 (equation 1) x-y=1 (equation 2). ...

2(x-y)=8 when x=6. All you need to do is to insert the given value of 'x' into the equation and solve for the unknown 'y':. The equation is: 2(x-y)=8 then they want you to solve for y when x=6 So, …

x + y = 8 x - y = 10 Algebra -> Matrices-and-determiminant -> SOLUTION: Given the system of equations, what is the value of the system determinant? Algebra: Matrices, determinant, …

-x + y = 8 - x + y = 12 Answer by rfer(16322) (Show Source): You can put this solution on YOUR website!-x ...
