Answer:
Step-by-step explanation:
5x - 16 = 4x + 6
x - 16 = 6
x = 22

4(22) + 6 = 88 + 6 = 94
Hello :
<span>7x-2y=1 ...(1)
2y=x-1...(2)
</span><span>substitution 2y in (1) :
</span>7x-(x-1) = 1
7x-x+1 = 1
7x = 0
x=0
in (2) : 2y = 0-1
2y = -1 y= -1/2
the <span>system have one solution : (0 ;-1/2)</span>
