Solve x+4y = 13 for x by subtracting 4y from both sides.
We end up with x = -4y+13.
Since x and -4y+13 are the same, we can replace every x in the first equation with -4y+13
2x-3y = -29
2( x ) - 3y = -29
2( -4y+13 ) - 3y = -29 ... x is replaced with -4y+13
The answer is choice B
It would be -50 because the rule is subtract by 2 then 4 then 6 then 8 and etc.
WARNING THIS IS THE WRONG ANSWER in case any of you look at this
Answer:
x = 101/4 or -3/2.
Step-by-step explanation:
(4x-101) (2x+3) = 0
4x - 101 = 0 or 2x + 3 = 0
4x = 101 or 2x = -3
x = 101/4 or -3/2.
Answer:
32n+38
Step-by-step explanation:
-2*-6n=12n
-2*-7=14
(12n+14)
3*8=24
3*7n=21n
12n+14+24+21n
32n+38
