Question

3(a-d)-2(a+b)4(x+y)+5(2x-y)2,4(c-3d)-1,3(2c-d)-3/4(-1/3m+n)-1/4(3m+n)

Answer 1

Вот но 4 хз как делать , сейчас конечно попробую гл не факт что смогу

Answer 2

Let's simplify the given expressions step by step:

a) 3(a - d) - 2(a + b)

Step 1: Distribute the numbers inside the parentheses. 3a - 3d - 2a - 2b

Step 2: Combine like terms (terms with the same variable). (3a - 2a) + (-3d - 2b)

Step 3: Simplify further. a - 3d - 2b

b) 4(x + y) + 5(2x - y)

Step 1: Distribute the numbers inside the parentheses. 4x + 4y + 10x - 5y

Step 2: Combine like terms (terms with the same variable). (4x + 10x) + (4y - 5y)

Step 3: Simplify further. 14x - y

c) 4(c - 3d) - 1

Step 1: Distribute the number 4 inside the parentheses. 4c - 12d - 1

d) 3(2c - d) - 3/4(-1/3m + n) - 1/4(3m + n)

Step 1: Distribute the numbers inside the parentheses. 6c - 3d - (3/4)(-1/3m) + (3/4)n - (1/4)3m - (1/4)n

Step 2: Simplify the fractions. 6c - 3d + (1/4)m + (3/4)n - (3/4)m - (1/4)n

Step 3: Combine like terms (terms with the same variable). (6c) + (-(3/4)m + (1/4)m) + ((3/4)n - (1/4)n) - 3d

Step 4: Simplify further. 6c - (2/4)m + (2/4)n - 3d

Step 5: Reduce the fraction (2/4) to (1/2). 6c - (1/2)m + (1/2)n - 3d

So, the simplified expressions are as follows:

a) a - 3d - 2b b) 14x - y c) 4c - 12d - 1 d) 6c - (1/2)m + (1/2)n - 3d
