what is the value of x in the equation 8x - 2y = 48, when y = 4?\n6\n7\n14\n48

Explanation:

Step1: Substitute y value

Substitute $y = 4$ into the equation $8x-2y = 48$, we get $8x-2\times4 = 48$.

Step2: Simplify the equation

$8x - 8=48$, then add 8 to both sides: $8x=48 + 8$, so $8x=56$.

Step3: Solve for x

Divide both sides of $8x = 56$ by 8, $x=\frac{56}{8}=7$.
