Hat is the value of x in the equation 7x + 2y = 48 , when y = 3?

x = 6

Step-by-step explanation:

When y = 3, we can use this value to substitute into the equation for 'y' in order to solve for 'x':

7x + 2(3) = 48  or 7x + 6 = 48

Subtract '6' from both sides: 7x + 6 - 6 = 48 - 6 or 7x = 42

Divide both sides by '7':  7x/7 = 42/7

Solve for 'x':  x = 6

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
