Value of x is 2 and y is 0 of the equations 2x + y = 4 and x - y = 2.
<h3>Define equation.</h3>
A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.
Given,
Equation:
2x + y = 4
x - y = 2
From equation 2,
x = 2 + y
Equating in equation 1,
Using substitution method,
2(2+ y) + y = 4
4 + 2y + y = 4
3y = 0
y = 0
x = 2 + y
x = 2+ 0
x = 2
Value of x is 2 and y is 0 of the equations 2x + y = 4 and x - y = 2.
