If y=11–x and 2x–y=4, we cannot find the value of x. Is this statement true or false?
True
False
y=11−x (given) On substituting the value of y in 2x−y=4, we get 2x−(11−x)=4 ⇒2x−11+x=4 ⇒3x=15 ⇒x=5 So we can find the value of x.
The polynomial (x2+a) cannot be factorized if a>0. Is this statement true or false?
Distance of any point (x, y) from the origin is x+y. True or False
In the given equations y=11–x and 2x–y=4, the value of x is 4.
x0=1y where x is ANY nonzero number and y is ANY integer. Say True or False
State true or false:
For a pair of equations 4x–y=19 and 2x+y=23, the value of 5y–2x will be 31, when the actual values of 'x' and 'y' are substituted.
