Question

point (-3,a+4) lies on graph of equation 3x=y+7a find the value of a, solution of equation

Answer 1

Step-by-step explanation:

Given

The value of x= -3

and value of y= a+4

Placing the value of x and y in given equation:

$3( - 3) = a + 4 + 7a \\ - 9 = 8a + 4 \\ - 9 - 4 = 8a \\ - 13 = 8a \\ a = \frac{ - 13}{8}$
