Answer:15x+7
Step-by-step explanation:
First you would see that the -(-10x+6) would turn into 10x+6 meaning that the whole equation would turn into 5x+1+10x+6. Then add the x numbers together and the whole numbers separate. So now your answer should be 15x+7
Answer:
<h3>x=9</h3><h3>y=12</h3>
Step-by-step explanation:
Plug x as 2y-15 in the first equation and solve for y.
-5(2y-15)+4y=3
-10y+75+4y=3
-6y+75=3
-6y=-72
<em>y=12</em>
Plug y as 12 in the second equation and solve for x.
x=2(12)-15
x=24-15
<em>x=9</em>
