1. -2(3x+4)
because -2 times 3= -6 and 4+4=8
Ok, so:
We have the following system of linear inequalities:
To solve this system, the answer is really simple:
"Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So, we're going to graph each inequality, and then find the overlapping portions of the solution regions.
In this case, we got the graph, so, we're going to analyze it.
We have these two lines:
8(2x-14)+13=4x-27
Use distribute property for the first one
16x-112+13=4x-27
16x-99=4x-27
12x=72
x=6. As a result, the value x is 6. Hope it help!
The simplified expression for the following expression are:
- 7a + 3a - 2a + 5a = 13a
- 0.7 - 0.3g - 0.02g + 5 = 5.7 - 0.32g
- 5g² + 3g - 4g + 5g² = 10g² - g
<h3>Simplification</h3>
7a + 3a - 2a + 5a
= 15a - 2a
= 13a
0.7 - 0.3g - 0.02g + 5
= 5.7 - 0.32g
5g² + 3g - 4g + 5g²
= 10g² - g
