Using the elimination method, the value of x in the system of equations is calculated as: 8.
<h3>How to Solve a System of Equations by Elimination?</h3>
To solve a system of equations given using the elimination method, do the following:
Multiply 2x - 5y = 1 by 2 and multiply -3x + 2y = -18 by 5 to get the following:
4x - 10y = 2 --> eqn. 1
-15x + 10y = -90 --> eqn. 2
Add
-11x = -88
Divide both sides by -11
x = 8

So 3 times a number is between -18 and 18
between means it cannot be -18 or 18 so
3 times x=3x
x=unknown
3x
< less than
>greater than
if it is between -18 and 18 then the number is >-18 and <18 so
-18<3x and
18>3x
divide both equations by 3
-6<x
6>x
combine
-6<x<6
solution set=(x|-6<x<6)
Answer:12
Step-by-step explanation: do you mean g+7-4 if you do then first you subtract 7 that gives us g-4=8 then you add 4 and that’s g=12
