3−2x=2x+3(6−3x)−7(1−2y)=25+6y

Zielflug [23.3K]

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= $\frac{5}{8}$

To solve for y: just use 14y=25+6y

Subtract both sides by 6y

8y=25

Then divide both sides by 8y

y= $\frac{25}{8}$
