The value of x is 7 and the value of y is 9.
<h3>What is an equation?</h3>
The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Use one equation to fully express one variable by the other, and then you use that identity in the second equation solving then for the second variable.
x = y - 2
7y = 4x + 35
The first equation is already an identity existing x by y. Then, we use this now in the second equation :
7y = 4(y - 2) + 35 = 4y - 8 + 35 = 4y +27
3y = 27
y = 9
The value of x will be calculated as below:-
x = y - 2 = 9 - 2 = 7
Therefore, the value of x is 7 and the value of y is 9.

Answer:
Jayna charges a lower hourly rate
Step-by-step explanation:
The THIRD statement is not true.
$2000 (spends a month)
The 5% of $2000 is only $100 for food.
The first statement is true "The household spend $260 per month on the car".
13 % of $2000 = $260
The second statement is true "The household spend $600 per month for rent".
30% of $2000 = $600
The fourth statement is also true "The household spend $200 in savings each month"
10% of $2000 = $200
