From the sum of 3x +4y -3xy and 5x +3y -2xy subtract the sum of 2x +y – 3xy and 10x -9y -8xy

(3x+4y-3xy+5x+3y-2xy)-(2x+y-3xy-10x-9y-8xy)=5x+7y-5xy-(-8x-8y-11xy)=5x+7y-5xy+8x+8y+11xy=13x+15y+6xy

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
