Answer:
Step-by-step explanation:
You first collect isolate all the variables
-3x+4/5=-2/3x+12
Subtract 4/5 from both side and add2/3x from both sides
-7/3x=56/5
You then multiply both sides by the reciprocal of the coefficient of the variable, in this case -3/7
-7/3x*(-3/7)=(56/5)*(-3/7)
x=-168/35
x=-24/5
Answer:
x=25°
Step-by-step explanation:
<u>Sum of angles of a triangle equals 180°</u>
- x + 10° + 2x + 15° + 3x + 5° = 180°
- 6x + 30° = 180°
- 6x = 180° - 30°
- 6x = 150°
- x = 150°/6
- x = 25°
Our current equation is:
2.5x -3.67 = 1.52.
To solve for x, we need to get x by itself and then simplify what we can from there.
2.5x -3.67 = 1.52
Add 3.67 to both sides to get 2.5x by itself.
2.5x = 5.19 is now our new equation.
Divide both sides by 2.5 to get x.
5.19/2.5 = 2.07
x = 2.07
I hope this helps!
