β 12y agoThose aren't math equations. An equation always has an equal sign, between two expressions.
Additional Information:-
If you meant: 2x+5y = 120 and x+y = 90
Then by a process of elimination: x = 110 and y = -20

β 12y agoWhen (the graph of the equations) the two lines intersect. The equations will tell you what the slopes of the lines are, just look at them. If they are different, then the equations have a unique solution..
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
The equation that is 56 plus 67 has an answer that is 123. You can solve simple equations like this one by using your calculator program on your computer.
Inconsistent linear equations in two variables.
The answer to that arithmetic is 4,568.Do the math. Yeah no kidding do the math.....again it is 4,691.

well +2=3

probaly anywhere!
A plus with a minus under it means "plus or minus" in math.
In math decrease means minus and increase means plus

Without any equality signs they can't be considered to be equations.
Inconsistent linear equations in two variables.
The two equations represent the same straight line.
There are several programs out there that actually make it like math is a videogame so they can have fun as they learn one such Math Missions that had an A plus rating.
