3(1) + 5 = 8

3+5 = 8

8=8

They are both equal, yes. The coordinates work out in the equation. Both sides are equal so the coordinates work. The answer is yes.

The sum of x and 3 times y is 5. The difference of x and y is 5. Write two equations and graph to find the value of y.
kupik [55]

Answer:

for the first one, x + 3 * y = 5

and the second equation, x - y = 5

Step-by-step explanation:

the sum of two numbers means for example the sum of 5 and 8 is 13, so as an equation that is 5 + 8 = 13

the difference is the same thing as the sum but it's subtraction.

and then times is just multiplication.
