(a+2)/3 =(a-1)/4

\frac{a + 2}{3} = \frac{a - 1}{4}

a = - 11

Solution steps

\frac{a + 2}{3} = \frac{a - 1}{4}

Apply fraction cross multiply: if

\frac{a}{b} = \frac{c}{d}

then

a \cdot d = b \cdot c

(a + 2) \cdot 4 = 3 (a - 1)

Expand

(a + 2) \cdot 4 : 4 a + 8

Expand

3 (a - 1) : 3 a - 3

4 a + 8 = 3 a - 3

Move

8

to the right side

4 a = 3 a - 11

Move

3 a

to the left side

a = - 11

- 19 + 2 z = - 21

x, x - 3 y = 5

x, x + y = 16

4 (x - 3) - 7 (x - 4) = 6 - x

6 - 3 (x + 1) = - 4 x + 2 (1 - x)
