Subtract 12(z+4)−3(14z+1) . Use fractions in final form.
To simplify the expression, we need to distribute the numbers outside the parentheses to the numbers inside.
12(z+4) - 3(14z+1)
= 12z + 48 - 42z - 3
Next, we can combine like terms.
= (12z - 42z) + (48 - 3)
= -30z + 45
The final form using fractions is -30z + 45.
