Step-by-step explanation:
Answer:2(r-5)
Step-by-step explanation: divide 2 on both sides which gives you 5 and then you write 2(r-5).
Hope it helps :)
2 is a factor of 4x + 2y
2( 2x + y)
5x + 2y = 7 ...multiply by -3
-2x + 6y = 9
-----------------
-15x - 6y = -21 (result of multiplying by -3)
-2x + 6y = 9
-----------------add
-17x = - 12
x = 12/17 or 0.7
5x + 2y = 7
5(12/17) + 2y = 7
60/17 + 2y = 7
2y = 7 - 60/17
2y = 119/17 - 60/17
2y = 59/17
y = (59/17) / 2
y = 59/17 * 1/2
y = 59/34 or 1.7
(0.7,1.7) is the solution to the equation....the question is asking for the y coordinate....it is 1.7 <==
