3 and the solution is x = -5 and y = -3
When subtracting the equations remember that a - - is equal to a +
So: - 6x - - 6x = 0
Also remember that a minus times a minus that the product is always a plus.
That word "equals" in there makes it an equation.
15 and -4
4800 you can just multiply 150x32
It's what number multiply by itself that equals the number you currently have。
Number density.
There is no need. The first equation can be rearranged to a simple equation in just y. Multiply it by 0.2 to solve for y. Substitute the value of y in the second equation and rearrange to get a simple equation in x. Multiply by (1/6) to find x.
One out of many examples of two step equations that equal 29 is: (9 x 3) + 2
Factors are the numbers you multiply together. For example, in the equation 2 times 3 equals 6, the 2 and the 3 are both factors of 6.

When you multiply a number by itself it equals the number in question to the power of two. For example, 4x4=16, but 4^2 also equals 16.
15 and -4
it equals the same number you multiply it by
1x21 7x3
4800 you can just multiply 150x32
It's what number multiply by itself that equals the number you currently have。
(+)(+)=(+) (-)(-)=(+) (-)(+)=(-) (+)(-)=(-) This is all.
Answer is 411 Logic: You multiply the two numbers in LHS of the equation and reverse the result to form the first two digits of RHS and for the 3rd digit you subtract one from the 2nd number on the LHS of the equation.
