Answer:
h = Hannah's age
h - 2 = Anthony's age
Hannah is 47, Anthony is 45
Step-by-step explanation:
Using one variable and an expression with the same variable, you can find the sum of the siblings ages:
h = Hannah's age
h - 2 = Anthony's age
h + (h - 2) = 92
Combine like terms: 2h - 2 = 92
Add '2' to both sides: 2h - 2 + 2 = 92 + 2 or 2h = 94
Divide by 2: 2h/2 = 94/2
Solve for h: h = 47 years old (Hannah)
h - 2 = 45 years old (Anthony)
A triangles angles all add up to 180*. so 90*+50*+40*=180*
Steps :-
■ Eliminate the equations (subtract them). You'll get the value of 1 variable.
■ Then substitute in another equation to get the value of the other variable.
Answer :-
■ x = -8 & y = 0
