Question

7x+5x=-48, 10y-7y=1,8, 6x- 0,8= 3x+2,2 решите пожалуйста ❤️

Answer 1

7x+5x=-42 / 12x=-48 / x=-48:2 / x=-24
10y-7y=1,8 / 3y=1,8 / y=1,8:3 / y=0,6
6x-0,8=3x+2,2 / 6x-3x=2,2+0,8 / 3x=3 / x=1

Answer 2

Solving the Equations

Let's solve the given equations step by step:

1. Equation 1: 7x + 5x = -48

Combining like terms, we get: 12x = -48

Dividing both sides by 12, we find: x = -4 2. Equation 2: 10y - 7y = 1.8

Combining like terms, we get: 3y = 1.8

Dividing both sides by 3, we find: y = 0.6 3. Equation 3: 6x - 0.8 = 3x + 2.2

First, let's simplify the equation: 6x - 3x = 2.2 + 0.8 3x = 3

Dividing both sides by 3, we find: x = 1 Therefore, the solution to the given system of equations is: x = -4 and y = 0.6.
