Answer:

Step-by-step explanation:
When subtracting polynomials, first start with distributing the negative sign to the second polynomial:

Simplify by combining like terms:

Answer:
<u><em>x=8.5 </em></u>
Step-by-step explanation:
you have to count the numbers at the top you get 22 then you subtract 22 from 39 that will get you 17 cut 17 in half and you will get 8.5 .so put 8.5 on both of the sides on the bottom.answer <u><em>x equals 8.5</em></u>
A given linear equation has infinitely many solutions.
<h3>What is a linear equation?</h3>
- There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that make a linear equation true and plot those values on a coordinate grid.
- As much as possible, reduce the equation to y = mx + b. Verify the exponents in your equation. It is nonlinear if it has exponents. Your equation is linear if there are no exponents in it.
- The definition of a linear equation is an equation with a maximum degree of one.
Given: −3y 3y 4 = 4
3y+4=3y+4
The given linear equation satisfies any value of 'y'.
So, A given linear equation has infinitely many solutions.
