Answer:
15
Step-by-step explanation:
52 - 4 =48
48 (divided) by 2 is 24 - 9 is 15 your welcome :D
3x-2=-x-6
do the inverse and add 2 to the whole number on the other side which is -6
3x=-x-4
do the inverse with the variable -x and add x to 3x
4x=-4
divide -4/4 since the inverse of multiplication is division
x=-1
Y=-2/3 x-2
y=-2x+2
We solved this equations system by equalization method.
-2/3 x -2=-2x+2
Least common multiple: 3
-2x-6=-6x+6
-2x+6x=6+6
4x=12
x=12/4=3
y=-2x+2
y=-2(3)+2=-6+2=-4
Solution: x=3; y=-4
To chek:
y=(-2/3)3-2=-4
y=-2(3)+2=-6+2=-4
