Answer:
13
Step-by-step explanation:
It's not 3.25 because if you simplify 6.5 and 0.5, you get 65 and 5 which if you divide is 13.
If the linear equations form parallel lines or if the answer is not true like 0=8 or 5=18 it means the linear equations have no solutions. If the linear equations form 2 lines that are on top of each other or the answer is true for example 0=0 or 5=5 then the linear equations will have infinitely many solutions. If a linear equation gives you a single answer like x= 7 an y=9 then the linear equation only has one solution
<span>- - Star to simplify both sides of the equation.
</span>
<span>- - Now you have top subtract 18 from both sides.
</span>
- - Solve:
<span>- - And divide both sides by -4.
- - Solve:

Answer:
x = 0
y = 1
Step-by-step explanation:
2x + 3y = 3 Multiply this equation by 3
3x + 5y = 5 Multiply this equation by 2
3(2x + 3y = 3)
6x + 9y = 9
2(3x + 5y = 5 )
6x + 10y = 10 Notice the xs are the same.
6x + 9y = 9
<u>6x + 10y =10 </u> Subtract
- y = - 1 Multiply each side by -1
y = 1
2x + 3y = 3
2x + 3*1 = 3
2x = 0
x =0
