Divide both sides of the equation 2 (x-1) = 3 (x-1) by X-1 at the same time to get 2 = 3. The reason for the error is that a. The equation itself is wrong. B. The equation has no solution. C. the two sides of the equation divided by 0 D.2 (x-1) is less than 3 (x-1)

Because the correct solution of C is x = 1 and then X-1 = 0, we can't choose C after division

The difference between half of X and 1 / 7 of X is equal to the sum of X and 1--------

(1/2)x-(1/7)x=x+1
(5/14)x=x+1
(-9/14)x=1
x=-14/9

The sum of 3 / 7 of X and 1.2 is equal to 2.3
1 / 2 is 10 more than 25% of the number. What is the number? 2 / 5 of a number is 0.5 more than 4. Find the number

2X / 7 = 2 / 3; X = 7 / 3; 3x / 7 + 1.2 = 2.3; 3x / 7 = 1.1; X = 7.7 / 3; X = 77 / 30; 1 / 2 is 10 more than 25% of the number. X / 2-0.25x = 10; 0.25x = 10; X = 40; 2 / 5 of a number is 0 more than 4

Who is bigger after seven out of nine and seven out of eleven? Who is bigger after five out of 26 and six out of 39?

7 out of 9
7 out of 9 = 77 out of 99
7 out of 11 = 63 out of 99
5 out of 26
5 out of 26 = 15 out of 78
6 out of 39 = 12 out of 78

A simple method of subtracting 2 out of 9 from 7 out of 8

2 out of 9 minus 2 out of 9
=2/9-2/9×7/8
=2/9×(1-7/8)
=2/9×1/8
=1/36

Simple calculation: 1 + 3 and 6:15 and 12:1 + 7 and 20:1 + 9 and 30:1 + 11 and 42:1=__

2587 out of 60

27 times 4 minus 12 minus 24 = 12 plus a matchstick or minus a matchstick to make the formula true

Add a match to the "1" in the rightmost "12" to make "1" become "7"
That is, the equation becomes: 27x4-12-24 = 72

(0.5) - (negative two and a quarter) + 3.75 - (five and a half)

(0.5) - (negative two and a quarter) + 3.75 - (five and a half)
=0.5+2.25+3.75-5.5
=6.5-5.5
=1

4 × 35.2-25.2 × 17.4 by simple method

I'm glad to answer your question
17.4×35.2-25.2×17.4
=17.4x(35.2-25.2)
=17.4x10
=174

Factorization factor - ax & #178; - ay

=-a(x^2+y)
