Answer:
the answer is additive inverse
Answer:
x = 20
Step-by-step explanation:
When a line is on two lines, it means they are congruent. This means they have the same value.
1.) Distribution 0.3(x-5) = 0.3x-1.5
2.) Combine like terms 0.2x and -2.1x ; -1.5 and 0.2
-1.9x + 3.1 = 0.3x -1.3
3.) Add 1.3 to both sides
-1.9x + 4.4 = 0.3x
4.) Add 1.9x to both sides
4.4 = 2.2x
5.) Divide both sides by 2.2 to isolate the variable.
x=2
Placed them equal to each other.
3x + 6 = 4x - 2
6 (+2) = 4x (-3x)
8 = x
plug in x to both of the expressions
3(8) + 6 = 24 + 6 = 30
4(8) - 2 = 32 - 2 = 30
True
x = 8

B is wrong, because you do not set them equal to 180 ( you set them equal to each other). Next, it is wrong, because they messed up the end too.
