Answer:
65
Step-by-step explanation:
So a number (let's call that x) plus -43 is 22. In an equation:
To find the number, add 43 to both sides. The left cancels:
And we're done!
Answer:
Question 1: x + 8 + 3x + 8 = 48
Question 2: Alicia is 8, her aunt is 24
Step-by-step explanation:
Question 1: 'x' represents Alicia's age. 3x is her aunt's age because her aunt is 3 times her age. In 8 years, their combined age will be 48. They each age 8 years, so x becomes x + 8, and 3x becomes 3x + 8
Question 2: solve the equation x + 8 + 3x + 8 = 48
4x + 16 = 48 (combine like terms)
4x = 32 (subtract 16 from both sides)
x = 8 (divide by 4 on both sides)
Since x is Alicia's age, she is 8, since 3x is her aunt's age, her aunt is 3(8) = 24
