we would then do the function h(x) = 2(26) +7

The equation 3x + 6 = 12 involves two operations performed on x: multiplication by 3 followed by addition of 6. What operations

BlackZzzverrR [31]

3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)

3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

$\frac{3x}{3}$ = $\frac{6}{3}$
3 and 3 cancels out
x = 2
