Answer:
You can either do distributive property to get X or you can divide 5 on one side and then divide the 5 on the other side. They both get 7=X
Step-by-step explanation:
Two ways to solve the expression are given below :
To solve the expression : 20 = 5(−3 + x)
First method :
20 = 5(−3 + x
Open the bracket :
20 = - 15 + 5x
Collect like terms
20 + 15 = 5x
35 = 5x
x = 35 /5
x = 7
Similarly :
20 = 5(−3 + x)
Divide bith sides by 5
20/5 = 5(−3 + x) / 5
4 = - 3 + x
Collect like terms
4 + 3 = x
x = 7
