Answer:

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

x=6 because if you plug 3 into y && multiply 3x2 equals 6 subtract that from 48 which is 42 && divide 42 by 7
