Question

Solve each equation. (would be nice if you could do work on a separate sheet of paper)

Answer 1

Answer:

Step-by-step explanation:

13) -10x = x -33

-10x - x = -33

-11x = -33

x = -33/-11

x =3

14)-10x - 11 = x - 33

-10x -x = -33 + 11

-11x = -22

x = -22/-11

x = 2

15) 4x + 4 = -3x - 17

4x + 3x = -17 -4

7x = - 21

x = -21/7

x = (-3)

16) 2x - 7 = 4x +12

2x - 4x = 12 + 7

-2x = 19

x = 19/-2

x = -19/2

17) 2x +7 = 4x +12

2x - 4x = 12 - 7

-2x = 5

x = 5/-2

x = -5/2

18) -2x +7 = -4x +12

-2x + 4x = 12 -7

2x = 5

x = 5/2

19) x + 5 = -3x -10

x + 3x = -10 - 5

4x = -15

x = -15/4

20) 15x +10 = 10x +10

15x - 10x = 10 - 10

5x = 0

x = 0

21)   $\frac{-1}{2}x$ = -x + 3

-x = 2*(-x + 3)

-x = -2x + 6

-x + 2x = 6

x = 6

22) $\frac{3}{4}x$ = x - 3

3x = 4 * ( x - 3)

3x = 4*x - 4*3

3x = 4x - 12

3x - 4x = -12

-x = -12

x = -12/-1

x = 12

23) $\frac{2}{3}x+1=\frac{-1}{3}x-1\\ \frac{2}{3}x+\frac{1}{3}x=-1-1\\ \frac{3}{3}x=-2\\ x=-2$

24) $\frac{1}{2}x+4=\frac{5}{2}x+2\\\frac{1}{2}x-\frac{5}{2}x=2-4\\ \frac{-4}{2}x=-2\\-2x=-2\\x=\frac{-2}{-2}\\ x=1$
