4(2y-1)-2(2y)=6

4 (2 y - 1) - 2 (2 y) = 6

y = \frac{5}{2}

Decimal Notation

y = 2.5

Solution steps

4 (2 y - 1) - 2 (2 y) = 6

Remove parentheses:

(a) = a

4 (2 y - 1) - 2 \cdot 2 y = 6

Multiply the numbers:

2 \cdot 2 = 4

4 (2 y - 1) - 4 y = 6

Expand

4 (2 y - 1) - 4 y : 4 y - 4

4 y - 4 = 6

Move

4

to the right side

4 y = 10

Divide both sides by

4

y = \frac{5}{2}

2 (4 x - 12) + 3 x = 6 x + 1

(9 x - 5)^{2} = 25

m^{2} + 18 m + 56

4 < x \leq 12

x (1 - x) \leq \frac{1}{4}
