Question

find the value of x-
8x/2= 48
25×3+x=86
2x+6/8= 7
16/y=2
5x-20/2=50
75+35+x=250
4(x-3)=56
x+2/5=6
​

Answer 1

Answer:

1) 8x/2=48

4x=48

x=48/4

x=12

Answer 2

Step-by-step explanation:

8x

$\frac{8x}{2} =48 \\ x = \frac{2(48)}{8} \\ x = 12$

$25 \times 3 + x = 86 \\ x =86 - 75 \\ x = 11 \\ 2x + \frac{6}{8} = 7 \\ 2x = 7 - \frac{6}{8} \\ 2x = \frac{56 - 6}{8} \\ x = \frac{50}{2(8)} \\ x = \frac{25}{8} \\ x = 3 \frac{1}{8}$

$\frac{16}{y} = 2 \\ y = \frac{16}{2} \\ y = 8 \\ 5x - \frac{20}{2} = 50 \\ 5x = 50 + 10 \\ x = \frac{60}{5} \\ x = 12 \\ 75 + 35 + x = 250 \\ x = 250 - 110 \\ x = 140$

$4(x - 3) = 56 \\ 4x - 12 = 56 \\ 4x = 68 \\ x = 17 \\ x + \frac{2}{5} = 6 \\ x = 6 - \frac{2}{5} \\ x = \frac{30 - 2}{5} \\ x = \frac{28}{5} \\ x = 5 \frac{3}{5}$
