Step-by-step explanation:
Given
- 5x + 3 = 2x - 1
or, 2x + 5x = 3 + 1
or, 6x = 4
or, x = 4/ 6
Therefore x = 2 /3
Hope it will help :)❤
True
<span>Cos(A+B)=CosACosB-SinASinB
therefore Cos(A+A)= CosACosA - SinASinA
= Cos^2A - Sin^2A</span>
Answer:
2
Step-by-step explanation:
Since there is nothing to solve in the absolute value, take them away and make -2x just 2x. To get x by itself, divide both sides by 2 to get x=2
the answer is d thats what im choosing because i recall doing a similar problem to this
I believe b and c don’t have a solution
