2+2X=?

when X = 2+5Y

when Y = 5*Z^2

when Z = 2

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 = ?

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
