Answer:
£0.85 for each
£1.70 for both
Step-by-step explanation:
Variable x = cost of baked beans
2.30 + 2(2.60) + 2x = 10 - 0.80
Use PEMDAS
2.30 + 5.20 + 2x = 10 - 0.80
7.50 + 2x = 9.20
Subtract both sides by 7.50
2x = 1.70
Divide both sides by 2 to isolate the variable
x = 0.85
Let's check our work by plugging this into our original equation
2.30 + 2(2.60) + 2(0.85) = 10 - 0.80
2.30 + 5.20 + 1.70 = 10 - 0.80
7.50 + 1.70 = 9.20
9.20 = 9.20
Our number is correct
The graph is given below. Then the intersection point will be (-9, 11).
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
An unknown number y is 20 more than an unknown number x.
The number y is also x less than 2.
The equations to find x and y are shown below:
y = x + 20 ...1
y = −x + 2 ...2
Add both equations, then we have
2y = 22
y = 11
Then put the value of y in equation 1, then we get
11 = x + 20
x = 11 - 20
x = -9
Then the intersection point will be (-9, 11)
