Question

4(5x+2)=10(2x-3)+15= 2(7x-7)=7(2x-3)+7=

Answer 1

4 (5х+2)=10 (2х-3)+15=-15

Answer 2

Let's solve these equations step by step:

1. 4(5x+2) = 10(2x-3) + 15

First, we need to distribute the multiplication on both sides of the equation:

20x + 8 = 20x - 30 + 15

Simplifying the right side of the equation:

20x + 8 = 20x - 15

Subtracting 20x from both sides of the equation:

8 = -15

This equation is inconsistent, which means there is no solution that can satisfy it.

2. 2(7x-7) = 7(2x-3) + 7

Again, we start by distributing the multiplication on both sides of the equation:

14x - 14 = 14x - 21 + 7

Simplifying the right side of the equation:

14x - 14 = 14x - 14

Subtracting 14x from both sides of the equation:

-14 = -14

This equation is true for any value of x, which means it has an infinite number of solutions.

Therefore, the solution to the equation is x = any real number.

I hope that helps!
