Answer 2

7×-14 - 18-48=72-9х+42
7х+9х=72-42+14+18+48
16х=110
х=6.875

Answer 3

To determine if the equation is linear, we need to check if the highest power of the variable (x) in the equation is 1. A linear equation has a degree of 1. Let's simplify the equation and see if it fits the criteria:

Given equation: 7(x – 2) – 6(3 – 8) = 9(8 - х) + 42

Step 1: Perform the operations inside the parentheses. 7(x - 2) = 7x - 14 -6(3 - 8) = -6(-5) = 30 9(8 - х) = 72 - 9x

Step 2: Substitute the simplified expressions back into the equation: 7x - 14 - 30 = 72 - 9x + 42

Step 3: Combine like terms: 7x - 44 = 72 - 9x + 42

Step 4: Move the x terms to one side of the equation: 7x + 9x = 72 + 42 + 44 16x = 158

Step 5: Isolate x by dividing both sides by 16: x = 158 / 16 x = 9.875

The value of x obtained from the equation is a constant, not a variable. Therefore, the given equation is NOT linear. It is a nonlinear equation since it contains x raised to a power other than 1 (x is raised to the power 0 in this case, which is why it's a constant term).
