Question

1/4(z+3z) + 7 = -z + 1 Distributive property algebra.

Answer 1

Answer:

z = -3

Step-by-step explanation:

There are four terms here.  Multiply each by 4 to remove the fractional coefficient 1/4:

z + 3z + 28 = -4z + 4

Combining the z terms, all on the left sides, we get 8z + 28 = 4, which simplifies to 8z = -24.  Then, dividing both sides by 8, we get z = -3 (answer)

Note:

We are using the Distributive Property of Multiplication here:

4(1/4)(z + 3z) + 4(7) = 4(-z + 1)
