Solve: negative 1 over 2 x + 1 = −x + 8 (5 points)
Naya [18.7K]
It is 14 because if you have -1/2x + 1 = -x + 8 you would combine the multiplied terms into a single fraction then subtract the one from both sides simplify till you get -x/2 = -x + 7 then you will add like terms so the x’s then you multiply all terms by two like 2(-x/2)= 2•7 then you can get 14.

PLEASE ANSWER + BRAINLIEST!!
GuDViN [60]
The answer would be B. 4m - 24n + 3.

To solve this, you line up each integer under the proper area. Simply move the positive 4 to the end of the bottom polynomial. Then solve.

17m - 13m = 4m
-12n - 12n = -24n
-1 + 4 = 3
Thus giving you an answer of 4m - 24n + 3 or B.

I hope this helps!

Graph the equations to solve the system. <br> y=3x+3<br> 1/3y+x+1
riadik2000 [5.3K]

Given equation is y=3x+3 and \frac{1}{3}y=x+1

Let's simplify the 2nd equation \frac{1}{3}y=x+1 before we can start graph so that calculation will be easy

\frac{1}{3}y=x+1

multiply both sides by 3 to cancel out fractions

3*\frac{1}{3}y=3*x+3*1

y=3x+3

which is exactly same as the first equation so graph of both will be exactly same and solution will be infinitely many solutions.

y=3x+3 has y-intercept 3 so first point will be (0,3). Slope is 3 so rise 3 unit up then 1 right and graph the new point.
