X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
Answer:
144
Step-by-step explanation:
5x + 4x = 7x + 32
9x = 7x + 32
2x = 32
x = 16
7(16) + 32 = 144
I think this is correct

Answer:
x=−18.849556r2+v/6.283185r
Step-by-step explanation:
Step 1: Flip the equation.
18.849556r2+6.283185rx=v
Step 2: Add -18.849556r^2 to both sides.
18.849556r2+6.283185rx+−18.849556r2=v+−18.849556r2
0r 2+6.283185rx=−18.849556r2+v
Step 3: Divide both sides by 6.283185r. 0r2+6.283185rx/
6.283185r = −18.849556r2+v/6.283185r
x=−18.849556r2+v/6.283185r
