Answer 1

7(1-х)<20-6(х+3)
7-7х<20-6х-18
-7х+6х<-7+2
-х<-5
х>5

Answer 2

To solve the inequality, follow these steps:

Step 1: Distribute the terms on the right side and simplify the expression. Step 2: Combine like terms. Step 3: Solve for 'x'.

Let's proceed with the calculations:

7(1 - x) < 20 - 6(x + 3)

Step 1: Distribute the terms on the left and right sides: 7 - 7x < 20 - 6x - 18

Step 2: Combine like terms on the right side: -7x < 2 - 6x

Step 3: Get all the 'x' terms on the left side and constant terms on the right side: -7x + 6x < 2

Combine the 'x' terms: -x < 2

Step 4: Now, we need to isolate 'x' by dividing both sides by -1. Remember that when dividing by a negative number, the inequality sign flips. x > -2

So the solution to the inequality is: x > -2
