Answer:
(1, 3)
Explanation:
The substitution method basically means you are replacing anywhere “y” shows up in the first equation with what y equals in the second, which is 3x in this case.
2x + 5y = 17
2x + 5(3x) = 17
So, instead of the y, you’d use 3x. After, you can multiply the 5 and the 3:
2x + 15x = 17
Because 2x and 15x both have x, you can combine them:
17x = 17
And finally, you can divide!
17/17 = 1
x = 1
After that, you just replace “x” with 1 in either equation to get y. The second is simpler, so that’s what I’ve used here.
y = 3x
y = 3(1)
y = 3
Therefore, your answer is (1, 3).
Hope this helps!
