Which of the following is a linear equation ?
2x + = 5
2x + = 2
x + 2y = 5(x - y)
+ = 25
Linear equations are equations whose degree is one. x+2y=5(x−y) Here the degree is one, so this is linear equation.
Which of the following pairs of linear equations is inconsistent? 1. x+3y–5=0, 2x+y=0 2. 2x+y=1, 2y=2–4x 3. 2x–y=2, 2y–4x=2
The linear equation 5x - y = 2x - 1 has
Which of the following is a linear equation?
i) x−2y=76
ii) x+78y3=98
iii) x2+2x−5=0
iv) x2+2x+2=0
