a=(4x-1)(x+3)-4x(x-1)+7x

a = (4 x - 1) \cdot (x + 3) - 4 x \cdot (x - 1) + 7 x

x = \frac{a + 3}{22}

Solution steps

a = (4 x - 1) (x + 3) - 4 x (x - 1) + 7 x

Switch sides

(4 x - 1) (x + 3) - 4 x (x - 1) + 7 x = a

Expand

(4 x - 1) (x + 3) - 4 x (x - 1) + 7 x : 22 x - 3

22 x - 3 = a

Move

3

to the right side

22 x = a + 3

Divide both sides by

22

x = \frac{a + 3}{22}

x, x + 5 y = - 21

\frac{1}{21} + \frac{1}{4} (3 x - 1) = 2 \frac{x}{3} - \frac{1}{2}

16 p - 12 = 42, p - 12

3 (7 - x) + 5 (x - 4) = 9

9 x + 7 = 2, 5 = 2
