What is 3x plus 2y equals negative 8?
3x + 2y = 8To solve P amount of variables, you need P equations. (e.g., for this problem you'd need two equations to actually solve for it.) However, with that said, there are an infinite amount of solutions that "work".First, solve for one of the variables. People are typically use to y=... form so:3x + 2y = 82y = 8 - 3xy = (1/2)(8-3x)y = 4-(3/2)x
What are the two numbers if the sum of two numbers is 82 and the difference is 36?
x = 59y = 23Let:x = the first numbery = the second numberx + y = 82 -- equation (1)x - y = 36 --- equation (2)By Elimination:x + y = 82x - y = 36=========2x = 118 2x/2 = 118/2x = 59x + y = 82y = 82 - xy = 82 - 59y = 23check:x - y = 3959 - 23 = 3636 = 36Let x = 1st numberlet y = 2nd numberX + Y = 82X - Y = 36add above equations2X = 118X = 59Y = 23
What is the answer to -10.25(8y-12)?
Multiplying out the brackets it is equivalent to: -82y+123
Which expression is not equivalent to 8 x 2 y?
82y 16x are both not equal to the given expression.
If the difference of a number is 6 and the sum is -2 what could the two numbers be?
8
