Answer: 14.5
Step-by-step explanation:
x=0 and y=
Step-by-step explanation:
We need to solve the system by elimination and find values of x and y
Subtract eq(1) and eq(2)
Now Multiply equation (1) by 2 and subtract with eq(2)
So, x=0 and y=

Top equation, minus 10 both sides to get
3x-2y=-10
bottom equation, minus 4x both sides
5y-4x=8
-4x+5y=8
now elimiate y's
multiply top equation by 5 and bottom equaiton by 2 and add them together
15x-10y=-50
<u>-8x+10y=16 +</u>
7x+0y=-34
7x=-34
divide both sides by 7
x=-34/7
sub back
3x-2y=-10
3(-34/7)-2y=-10
(-102/7)-2y=-10
add (102/7) to both sides
-2y=-10+(102/7)
-2y=(-70/7)+(102/7)
-2y=32/7
divide both sides by -2, or times both sides by -1/2
y=-32/14
y=-16/7
(x,y)
(-34/7,-16/7)
Answer:
x = 28/5
Step-by-step explanation:
We can use proportions to solve
5x 7
------ = ---------
8 2
Using cross products
5x*2 = 7 * 8
10x = 56
Divide by 10
10x/10 = 56/10
x = 28/5
