Answer:
Step-by-step explanation:
ABC is the sum of the angles CBD and ABD. So:
Substitute them for their equations:
Solve for x. Combine like terms on the right:
Add 11x to both sides:
Subtract 241 from both sides:
Divide both sides by 4:
The value of x is 9.
And we're done!
Answer: -8
Step-by-step explanation:
Solve for x
5 (x − 2) = 3 (x − 4) − 14
5x − 10 = 3 (x − 4) − 14
5x − 10 = 3x − 12 − 14
5x − 10 − 3x = −26
2x = −26 + 10
2x = −16
x = −8
Just distribute -5
30u+15x-20
Don’t forget to change negative signs to positive signs if their multiplied by negatives
Answer:
Step-by-step explanation:
−2/9x+2.7=4
subtract 2.7 from both sides
-2.9x = 1.3
divide -2.9 from both sides
x= -.4482 or x= -.45
