Ok i know that 6x divided by 42 would be 6 so were left with y=3. Do you know what the next step is?
Answer:

Step-by-step explanation:


Putting value of eq. 1 in the following:

Answer:
x = 8 cm
Step-by-step explanation:
Given that,
In a square PQRS, PQ = 2x +3 cm and QR = 3x – 5 cm.
We need to find the value of x.
In a square, all the sides are equal. So,
PQ = QR
2x +3 = 3x – 5
3+5 = 3x - 2x
x = 8
So, the value of x is equal to 8 cm.
42. Because you separate 6 and 7. and 6 can be broken into 2 and 3. SO 2 times 3 times 7.
