N/5 + 0.6=2
We simplify the equation to the form, which is simple to understand n/5 + 0.6=2
We move all terms containing n to the left and all other terms to the right. + 0.2n=+2-0.6
We simplify left and right side of the equation. + 0.2n=+1.4
We divide both sides of the equation by 0.2 to get n. n=7
–2x + 4y = –7 . . . . . (1)
y = -1/2x + 5 . . . . . . (2)
Putting (2) into (1), we have:
-2x + 4(-1/2x + 5) = -7
-2x - 2x + 5 = -7
-4x = -7 - 5 = -12
x = -12/-4 = 3
y = -1/2(3) + 5 = -3/2 + 5 = 7/2
Hence, the system has one solution.
