Answer:
8yz+xy
like terms and then solve it
Let the smaller number be x and the larger be (x+19)
x+x+19=35
2x=16
x=8
x+19=27
the numbers are 8 and 27.
Answer:
We need to find a relationship between the equations.
Let's solve for one variable.
2x + 2y = 15
2y = 15 - 2x
We know what 2y is in relation to x. Now we can solve.
2x + 15-2x = 15
15 = 15
Unless there are more equations, this is your answer. For it to be simultaneous you need more than one equation.
The problem is actually already factored for you. They are asking you to just set the equation to zero. Find the zeros.
