x = 4 and y = 7

You would need to know what a is equal to in order to calculate this equation.

Choose any value for "x", replace that in the equation, and calculate the corresponding value for "y".

The solution pair is (-7, 22), demonstrated as follows: (1) x + y = 15 : given; (2)4x + 3y = 38 : given; (3)3x + 3y = 45 : equation (1), multiplied by 3; (4) x = -7 : equation (2), minus equation (3); (5) y = 22 : equation (1), minus equation (4).

1. simple keep change change, changing it from -2--3 to -2+3=1 or to switch that order to make it even easier on yourself you can make it 3-2=1 but be careful with your signs when switching the order of numbers in the equation. the answer is 1.

It is: (6-3)*(7+4) = 33

Adding a negative number to a negative number makes a larger negative. In order to solve this you add the numbers together as a positive then add a negative sign.

This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.

Multiply by 4

In order to answer that, we need an "equation" that shows us the relationship among 'Y', 'A', and 'B'.

13 + 7 - (6 + 4) * 2 = 0

It works out that: x = 3 and y = 2
