the required equation will be:
-5( 7w+ 8)= 30
-35w- 40= 30
-35w= 30+ 40( as 40 is taken to the other side, its symbol changes)
-35w= 70
W= 70/-35
W= -2
it can be used to calculate the length of a circular bracelet
Solve the system using substitutions:
x has a value of 1. Use this value to find the value of y.
y has a value of 1.
x=1
y=1
