Answer:
x = 12
Step-by-step explanation:
Given
EF = 10x +20
FG = 43
EG = 183
The following expression is true for the given datas.
EF+FG = EG
Substitute the given data into the expression
(10x+20)+43 = 183
Solve for the unknown value x
10x+63 = 183
10x = 183-63
10x = 120
Divide both sides by 10
10x/10 = 120/10
x = 12
Hence the value of x is 12.
