2 y 3 y 9 if you know you know homie
2(3x+7)+x=70
mutiply the bracket by 2
(2)(3x)(2)(7)+x= 70
6x+14+x= 70
6x+x+14= 70 ( combine like terms)
7x+14= 70
move 14 to the other side
sign changes from +14 to -14
7x+14-14=70-14
7x= 56
divide both sides by 7
7x/7= 56/7
x=8
Answer: x= 8
Answer:
There is no solution because the graphs do not intersect
Step-by-step explanation:
Both of theses equations do intersect with one another when graphed. In conclusion, there is no solution.
Answer:
<h2>y = -4x</h2>
Step-by-step explanation:
Solve 20x + 5y = for y
20x + 5y = 0
subtract 20x both sides
5y = -20x
simplify:
y = <u>-20x</u>
5
finally
y = -4x
Answer:
Step-by-step explanation:
