Step-by-step explanation:
- (a) 4(x+10)= 5-x
- Here, x = 7
- 4(7+10) = 5-7
- 28+40 = -2
- 68 is not = to -2
- (b) Here, x= -7
- 4(-7+10) = 5-(-7)
- -28+40 = 5+7
- 12 = 12
- (c) Here, x= 5
- 4(5+10) = 5-5
- 20+40 = 0
- 60 is not = to 0
- (d) Here, x= -10
- 4(-10+10) = 5-(-10)
- -40+40 = 5+10
- 0 is not = to 15
Hence option (b) satisfies this equation.
