Step-by-step explanation:

1 find out what kind of  its is

if its equivelent you might use 60 as thee angles then find out

Equation obtained from the question.

4x² + 2y = 8 .............(1)

2x² = 7..... (2)

Determination of the value of x².

From equation 2,

Divide both side by 2

Determination of the value of y

From equation 1,

Clear bracket

Collect like terms

Divide both side by 2

Therefore, the value of y is –3
