Solve by elimination
-3x+2y=10
-2x-y=-5

Answers

Answer 1
Answer: First you need to get two similar terms to eliminate, I'll do y:
-3x + 2y = 10
-4x - 2y= -10
And then you minus
x = 20
Now you can substitute x in to one of the equations to find y:
-60 + 2y = 10
+ 60
2y = 70
÷ 2
y = 35
So your values are y = 35 and x = 20. Hope this helps!

What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Total tuition fees;

6 × 530 = $3180

Books cost = $1800

Total cost to get a degree = Total tuition fees + Books cost

Total cost to get a degree = 3180 + 1800 = $4980.

Hence "The total cost for Neil to get his degree is $4980".
