$4y^2+2=(4y\cdot4y)+2\\
4y^2+2=16y^2+2 \leftarrow \text{not identity}\\\\
4y^2+2=(4y+y)+2\\
4y^2+2=5y+2 \leftarrow \text{not identity}\\\\
4y^2+2=4(y+y)+2\\
4y^2+2=8y+2 \leftarrow \text{not identity}\\\\
4y^2+2=4(y\cdot y)+2\\
4y^2+2=4y^2+2 \leftarrow \text{identity}$

So it's D.

Linear System, substitutional method 5x+4y=32 9x-y=33 helppp

Pachacha [2.7K]

5x + 4y = 32 ⇒ 45x + 36y = 288
9x - 1y = 33 ⇒ 45x - 5y = 165
 41y = 123
 41 41
 y = 3
 5x + 4(3) = 32
 5x + 12 = 32
 - 12 - 12
 5x = 20
 5 5
 x = 4
 (x, y) = (4, 3)
