Question

find the value of y for 4x-y=10 if x=1​

Answer 1

Answer:

• Value of y for 4x - y = 10 if x = 1, is -6.

Step-by-step explanation:

Given that:

• Value of x = 1.

To Find:

• Value of y for: 4x - y = 10

Solution:

Substituting the value of x to the equation,

$\sf{\longmapsto(4\times1)-y=10}$

$\sf{\longmapsto4-y=10}$

Now, solving the equation to find the value of y,

$\sf{\longmapsto4-y=10}$

$\sf{\longmapsto-y=10-4}$

$\sf{\longmapsto-y=6}$

$\sf{\longmapsto y=-6}$

Hence,

• Value of y = -6

Verification:

Verifying for x = 1 and y = -6:

LHS:

$\sf{\longmapsto4x-y}$

$\sf{\longmapsto(4\times1)-(-6)}$

$\sf{\longmapsto4+6}$

$\sf{\longmapsto10}$

RHS:

$\sf{\longmapsto10}$

As,

• LHS = RHS

Hence, Verified.
