(x)+(x+3)+(x-2)+3(x+3)-1=87

(x) + (x + 3) + (x - 2) + 3 (x + 3) - 1 = 87

x = 13

Solution steps

(x) + (x + 3) + (x - 2) + 3 (x + 3) - 1 = 87

Remove parentheses:

(a) = a

x + x + 3 + x - 2 + 3 (x + 3) - 1 = 87

Group like terms

x + x + x + 3 (x + 3) + 3 - 2 - 1 = 87

Add similar elements:

x + x + x = 3 x

3 x + 3 (x + 3) + 3 - 2 - 1 = 87

3 - 2 - 1 = 0

3 x + 3 (x + 3) = 87

Expand

3 (x + 3) : 3 x + 9

3 x + 3 x + 9 = 87

Add similar elements:

3 x + 3 x = 6 x

6 x + 9 = 87

Move

9

to the right side

6 x = 78

Divide both sides by

6

x = 13

53 k - 3 = 13 + 2 k

x, 7 x - y = 2

x, 7 x - y = 4

3 = \frac{v}{- 6}

2 x = \frac{1}{2}
