Answer:
1) -5 = x
2) 1 = x
3) 4⅘ = x
4) 6 = x
5) 7½ = x
6) 1⅒ = x
7) ⅜ = x
Step-by-step explanation:
7) 3x + ¾ = x + 3⁄2
- 3x - 3x
__________________
¾ = -2x + 3⁄2
-3⁄2 - 3⁄2
___________
-¾ = -2x
___ ____
-¾ -¾
[tex] \frac{3}{8} = x[/tex]
6) x + ⅘ = 3 - x
- x - x
_______________
⅘ = 3 - 2x
-3 - 3
__________
-2⅕ = -2x
____ ___
-2 -2
[tex]1 \frac{1}{10} = x[/tex]
5)
[tex] \frac{x}{3} - \frac{3}{4} = \frac{7}{4} >> \frac{4x}{12} - \frac{9}{12} = \frac{21}{12} >> 7\frac{1}{2} = x[/tex]
4) ˣ⁄2 + 4 = 7
- 4 - 4
__________
ˣ⁄2 = 3
[tex]6 = x[/tex]
3)
[tex]x + (12 - 3x) = 3 - (5 - x)3 \\ \\ 12 - 2x = 3 - 15 + 3x >> 12 - 2x = -12 + 3x[/tex]
12 - 2x = -12 + 3x
- 3x - 3x
__________________
12 - 5x = -12
-12 - 12
_____________
-5x = -24
___ ___
-5 -5
[tex]4 \frac{4}{5} = x[/tex]
2) 4x + 11 = 17 - 2x
- 4x - 4x
____________________
11 = 17 - 6x
-17 -17
____________
-6 = -6x
__ ___
-6 -6
[tex]1 = x[/tex]
1) 2x + 13 = x + 8
- 2x - 2x
________________
13 = -x + 8
- 8 - 8
____________
5 = -x
[tex] -5 = x[/tex]
