3 (22-4)=7- (z +5）

Answer 1

To solve the equation $3(22-4)=7-(z+5)$, we will follow these steps:

First, simplify the left side:

$$3(22-4)=3\times 18=54$$

Now, simplify the right side:

$$7-(z+5)=7-z-5=2-z$$

Now we have the equation:

$$54=2-z$$

Next, isolate $z$. First, subtract 2 from both sides:

$$54-2=-z$$

This simplifies to:

$$52=-z$$

Now, multiply both sides by -1 to solve for $z$:

$$z=-52$$

Thus, the solution is:

$$z=-52$$
