No. Substitute the value 8 for x, and you have 4x +6 = 4(8) +6 = 32 +6 = 38.
46
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
X equals 6 ..
x=-4.6
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
Yuuuh suucck x)))))))
x + 6
x + 36 = 82x = 82 - 36x = 46
X equals 9.
Expanded Notation of 46 = (4 x 10) + (6 x 1)
(x, y) = (-6, 0)
