Answer 1

4(х-5)-(7х+9)=1
4х-20-7х-9=1
4х-20-7х-9-1=0
-3х-30=0
-3х=30
х=-10

Answer 2

Solution:

To solve the linear equation 4(x-5) - (7x+9) = 1, we can follow these steps:

Step 1: Simplify the equation by distributing and combining like terms. - Distribute the 4 to both terms inside the parentheses: 4x - 20 - (7x + 9) = 1. - Remove the parentheses: 4x - 20 - 7x - 9 = 1. - Combine like terms: -3x - 29 = 1.

Step 2: Isolate the variable term. - Add 29 to both sides of the equation: -3x = 1 + 29. - Simplify: -3x = 30.

Step 3: Solve for x. - Divide both sides of the equation by -3: x = 30 / -3. - Simplify: x = -10.

Therefore, the solution to the linear equation 4(x-5) - (7x+9) = 1 is x = -10.
