3x+8(x-1)=47

3 x + 8 (x - 1) = 47

x = 5

Solution steps

3 x + 8 (x - 1) = 47

Expand

8 (x - 1) : 8 x - 8

3 x + 8 x - 8 = 47

Add similar elements:

3 x + 8 x = 11 x

11 x - 8 = 47

Move

8

to the right side

11 x = 55

Divide both sides by

11

x = 5

x - a = b

c, f = 7 c - \frac{c}{d}

x, x - 4 y = - 6

6 k - 17 = 37

y = \frac{1}{2} 0
