Answer:
2x-1=x+1
2x-x=x
1+1=2
x=2
Knowing x's value, we substitute it with the equations
y=x+1
y=2+1
or y=2x-1
y=2(2)-1
y=4-1
y=3
(2,3) are your coordinates :D
Answer:
Streamers are $2.50 each
Balloons are $1.50 each
Step-by-step explanation:
Make a system of equations
3s + 15b = 30
2s + 4b = 11
Solve by elimination: multiply the top equation by 2 and the bottom equation by -3.
6s + 30b = 60
-6s -12b = -33
18b = 27
b = 1.5
Plug in 1.5 as b to find s
3s + 15(1.5) = 30
3s +22.5 = 30
3s = 7.5
s = 2.5
The streamers are $2.50 and the balloons are $1.50
Answer:
50
Step-by-step explanation:
<em>Substitute</em> 7 as x in the original equation, (9x-13)
<u>9(7)-13</u>
1) Multiply 9 and 7:
63-13
2) Subtract:
50
