Can you give me the brainliest?
we can find the y first
as we know z = 2 we can put it in the equation y = 5*z^2
y = 5 (2) ^2
y = 5 (4)
y = 20
now we can put the value of y into X = 2+5Y
X = 2+5 (20)
X = 2 + 100
X = 102
now we can put the value of x in 2+2X=?
=2+2 (102)
= 2 + 204
= 206
so 2 + 2x = 206

Since you know Z = 2, you can plug it into:
Y = 5 · Z²
Y = 5 · (2) ²
Y = 5 · 4
Y = 20
Now that you know Y = 20, you can plug it into:
X = 2 + 5Y
X = 2 + 5 (20)
X = 2 + 100
X = 102
Now that you have X, plug it into "2+2X=?"
2 + 2x = ?
2 + 2 (102) = ?
2 + 204 = ?
206 = ?
