2. -2x-4=-18, -2x=-18+4, -2x=-14, -2x/-2=-14/-2, x=7
3. 3(x-4)=-18, 3x-12=-18, 3x=-18+12, 3x=-6, 3x/3=-6/3, x=-2
4. (x-5)=-7, 1x=-7+5, 1x=-2, 1x/1=-2/1, x=-2
1. -2x=-8, -2x/-2=-8/-2, x=4
2. -2x-4=-18, -2x=-18+4, -2x=-14, -2x/-2=-14/-2, x=7
3. 3(x-4)=-18, 3x-12=-18, 3x=-18+12, 3x=-6, 3x/3=-6/3, x=-2
4. (x-5)=-7, 1x=-7+5, 1x=-2, 1x/1=-2/1, x=-2
Answer:
1. x=4
2. x=7
3. x=-2
4. x=-2
5. x=-3
Step-by-step explanation:
1. Divide both sides by -2 to get x by itself
-2x/-2=-8/-2....
x=4
2. Add 4 to both sides and then divide by -2
-2x-4+4=-18+4
-2x/-2=-14/-2
x=7
3. Distribute, add 12 to both sides and then divide by 3
3x-12=-18
3x-12+12=-18+12
3x/3=-6/3
x=-2
4. Add 5 to both sides
x-5+5=-7+5
x=-2
5. Distribute, add 4 to both sides, divide both sides by 4
4x-4=-16
4x-4+4=-16+4
4x/4=-12/4
x=-3
