2(4a-12)+3a=6a
Multiply the bracket by 2
(2)(4a)=8a
(2)(-12)=24
8a-24+3a=6a
8a+3a-24=6a ( combine like terms)
11a-24=6a
Move 11a to the other side. Sign changes from +11a to -11a.
11a-11a-24=6a-11a
-24=6a-11a
-24=-5a
Divide both sides by -5
-24/-5=-5a/-5
Answer: a=24/5 or a= 4 4/5 or in decimal x=4.8
5x - 5 = x + 15
add 5 to both sides
5x = x + 20
subtract x from both sides
4x = 20
divide both sides by 4
x = 5
Answer:
Step-by-step explanation:
you put the -9 above where it says the -9 and same to the -3
or to solve the equation:
Divide both sides of the equation by the same term
−9=−3−9−3=−3−3
Divide the numbers
−9−3=−3−3
3=−3−3
Cancel terms that are in both the numerator and denominator
Move the variable to the left =3x=3
Solution =3
The line x=3.5 is a vertical line passing through 3.5 on the x-axis . Itercept is 3.5
The line y=-6.5 is a horizontal line passing through - 6.5 on the y-axis it’s intercept is - 6.6
