Answer:
x = 4
Step-by-step explanation:
13x=32+5x
Subtract 5x from each side
13x-5x=32+5x-5x
8x = 32
Divide each side by 8
8x/8 = 32/8
x = 4
for example, let's look at the first set
y+3x =5 or y = -3x+ 5
and y = -3x + 2
y = m + b
the slopes are equal, the y-intercepts differ
that means, they're just parallel lines, no solution
Answer:
She sold 3 computer games and 4 board games.
Step-by-step explanation:
If I am doing this right you subtract 9 from 43 until you get the lowest number that you can subtract 9 from 43 thats goes into 4. You then subtract 4 until you get 0.
Sorry if this is confusing I didn't know how to explain it well.
Y = -5x + 9
y = 5x + 7
5x + 7 = -5x + 9
5x + 5x = 9 - 7
10x = 2
x = 2/10 reduces to 1/5
y = 5x + 7
y = 5(1/5) + 7
y = 1 + 7
y = 8
solution is (1/5,8)
