Make an equation system based on the problem
eg. a is the first number and b is the seond number
An equation for "<span>The sum of two numbers is 53" is
</span>⇒ a + b = 53
An equation for "<span>twice the first number minus three times the second number is 26"
</span>⇒ 2a - 3b = 26
<span>
Solve the equations by elimination and subtitution method
Eliminate a to find the value of b
a + b = 53 (multiplied by 2)
2a - 3b = 26
--------------------------------------
2a + 2b = 106
2a - 3b = 26
------------------- - (substract)
5b = 80
b = 80/5
b = 16
Subtitute the value of b to one of the equations
a + b = 53
a + 16 = 53
a = 53 - 16
a = 37
The numbers are 16 and 37</span>
Answer: i don't need the money but i can try to help you
Step-by-step explanation:
Okay! You’re a girl right? Lol
In the division a/b, a is the dividend, and b is the divisor.
In this problem, 2/3 is the dividend, and 4/5 is the divisor.
She needed to multiply the dividend, 2/3, by the reciprocal of the divisor, 5/4.
Instead, she multiplied the dividend by the divisor without using the reciprocal.
Answer: second choice
