Answer:
A two-step equation is something like:
A*X + B = C
In this case, like in a linear equation, we have only one solution that can be found as:
A*X = C - B
X = (C - B)/A
In the case of a two-step inequality, we have something like:
A*X + B > C
Solving this we get;
A*X > C - B
X > (C - B)/A
In this case, any value of X that is larger than (C - B)/A is a solution, so in this case, we have infinite solutions.
That is the difference between the number of solutions for each case, in a two-step equation we have only one, while in the case of the inequality we have infinite.
Answer:
<u>The sum of the two equations is 8x + 5 and the value of x is -5/8</u>
Step-by-step explanation:
Let's add these two equations and solve for x:
2x + 6 + 6x - 1 = 0
8x + 5 = 0
8x = -5
<u>x = -5/8</u>
<u>The sum of the two equations is 8x + 5 and x = -5/8</u>
Answer:
Step-by-step explanation:
d + 2d - 8 = 46
3d - 8 = 46
3d = 54
d = 18
Plug the -1 in the x values
3(-1)-5
-3-5
= -8
X=3.1:
