Answer:
1. x=-5
2. x=24
3. -1x+19
4. 14w²-4w
5. 5x-15
6. 11a²b-12ab²
7. 6x+4
8. x=15
9. x=-12
10. x=3
11. x=20
Step-by-step explanation:
1.
15x-24-4x=-79 We have to add the like terms
+24 +24
15x-4x=-55 Subtract 15x-4x
11x=-55 Now divide
/11 /11
x=-5
2.
3(2x-5)-4x=33 Use distributive property
6x-15-4x=33 Add like terms
+15 +15
6x-4x=48 Subtract 6x-4x
2x=48 Divide
/2 /2
x=24
3.
6x+4+15-7x Combine 6x and -7x
-1x+4+15 Now combine 4 and 14
-1x+19
4.
6w²+11w+8w²-15w Combine 11w and -15w
6w²+8w²-4w Now combine 8w² and 6w²
14w²-4w
5.
12x-5-7x-11 Combine -5 and -11
12x-7x-15 Now subtract 12x-7x
5x-15
6.
11a²b-12ab²
Nothing else can be done with this equation
7.
2(3x+2)
6x+4
8.
x/5=3
5×3=15
15=x
9.
2/3x=-8
-4×2=-8
-4×3=-12
x=-12
10.
9x-11=-38
+11 +11
9x=-27
/9 /9
x=3
11.
-x/5+3=7
-3 -3
-x/5=4
-x=-20
x=20
