4. find x if pq = rs,
pq = 9x - 7, and rs = 29.

We have that The soultion of x is mathematically given as

x=12

From the question we are told

Generally the equation for the statement is mathematically given as

Since

Therefore

The solution of x is mathematically given as

x=12

x=4

Step-by-step explanation:

Because we know that PQ = RS, we can use the transitive property to replace PQ in the first equation with 29:

9x-7=29

1) Add 7 to both sides:

9x=36

2) divide by 9 on both sides:

x=4
