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=![\frac{5}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D)
To solve for y: just use 14y=25+6y
Subtract both sides by 6y
8y=25
Then divide both sides by 8y
y=![\frac{25}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B8%7D)
12/3 = 4
