If you mean: x+y = 8 and -x+2y = 7 then they are simultaneous equations whose solutions are x = 3 and y = 5
1,4,6,4,1
It is an algebraic expression because it does not contain an equality sign.
If you mean: 9x-2y = 7 then it is y = 4.5x-3.5
Literal coefficients are the non-numeric multipliers of expressions (or terms). In this case, they are x and y.
2 and 5 are coefficients of x and y respectively.
Multiply the first equation by 3 to give 9x + 15y = 21
In the expression '15b + 23b + 10', the coefficients are 15, 23, and 10.If you simplify the expression to '38b + 10", then the coefficients are 38 and 10.
Standard form would be x and y on one side of the equal sign with no coefficients. x-y+6=0 in standard form would be: x-y=-6.
The expression 3y + 2y + y simplifies to 6y. This is because when you add like terms (terms with the same variable, in this case y), you add the coefficients (numbers in front of the variable) together. In this case, 3y + 2y = 5y, and then adding another y gives you 6y.
If you mean: x+y = 8 and -x+2y = 7, then they are simultaneous equations whose solutions are x = 3 and y = 5.
Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12
