3x + 2 = 4x - 3
4x - 3x = 2 +3
x = 5
2y +7 = 4y - 9
4y - 2y = 7+9
2y = 16
y = 2
9)
2x - 2 = x + 2
2x - x = 2+2
x =4
5y - 8 = y+24
5y - y = 24 +8
4y = 32
y = 8
Answer:
.75
Step-by-step explanation:
75%
because it will give 100
Answer:
x=16 and y=9
Step-by-step explanation:
2y+30=3y+21[Diagonals of parallelogram are equal]
30-21=3y-2y
y=9
3y=2x-5[Diagonals of parallelogram are equal]
3×9=2x-5
27=2x-5
2x=27+5
x=32/2=16
I tried every combination. there seems to be something wrong with the informations you gave.
the second equation contains errors, and none of these 4 points can be solutions to the first equation alone
