Answer:
Step-by-step explanation:
First you need to use the distributive property:
3-2x+2x+3(6-3x)-7(1-2y)=25+6y
3-2x=2x+18-9x-7+14y=25+6y
3-2x=-7x+11+14y=25+6y
Then Split up the equations.
3-2x=-7x+11
Subtract 3 from both sides
-2x=-7x+8
Then add -7x to both sides
5x=8
Then divide both sides by 5x
X=
To solve for y: just use 14y=25+6y
Subtract both sides by 6y
8y=25
Then divide both sides by 8y
y=
I’m sorry but I think you forgot to attach the picture of the problem to your question
N/d = 15
d= 4 + 3n
d=n/15
n/15=4+3n
n=60+45n
44n=-60
n=-15/11
-15/11 / d = 15
-15/11 = 15d
d=-1/11
15/11 / 1/11. = 15
