Answer:
x = 10.353, y = 8.706
Step-by-step explanation:
2x+y = 28 eqn..(1)
–3x+7y = 26 eqn..(2)
Transpose y in eqn(1), which is;
2x+y = 28; y = 28–2x
Plug in y in eqn(2)
–3x+7(28–2x) = 26
–3x–14x+196 = 26
–17x = 26–196
–17x = –176
x = 10.353
plug in x in any of the eqn..
2(10.353)+y = 28
20.706+y = 28
y = 28–20.796
y = 8.706
