simplify (2y-3)-(4y-5)

simplify

(2 y - 3) - (4 y - 5)

- 2 y + 2

Solution steps

(2 y - 3) - (4 y - 5)

Apply rule:

(a) = a

(2 y - 3) = 2 y - 3

= 2 y - 3 - (4 y - 5)

Apply the distributive law:

- (a - b) = - a + b

- (4 y - 5) = - 4 y + 5

= 2 y - 3 - 4 y + 5

Group like terms

= 2 y - 4 y - 3 + 5

Add similar elements:

2 y - 4 y = - 2 y

= - 2 y - 3 + 5

Add the numbers:

- 3 + 5 = 2

= - 2 y + 2

x^{2} y^{2} + 5 x y - 36

(a - b - c)^{3}

\frac{1}{( a ^{l o g_{b} (a)} )}

f^{- 1} g (x)

(3 \frac{a}{2} + \frac{b}{4} - 2 c)^{2}
