Answer:
(0,1)
Step-by-step explanation:
There is a solution where the two equations intersect, therefore:
3x+1=2x+1
3x-2x=1-1
x=0
If we plug this 0 value into the x of both equations, we get a y value of 1:
y=3*0+1
y=0+1
y=1
OR
y=2*0+1
y=0+1
y=1
Therefore, there is a solution at (0,1)

Step-by-step explanation:
Graph the line using the slope and y-intercept, or two points.
slope:1
y-intercept: (0,-8)
x | y
--------------------
0 | -8
1 | -7

Answer:
15 years old
Step-by-step explanation:
The equation would be
8x + 2x + x = 53
3x = 45
x = 15
Take his age, subtract off 12 and you get the sister's age
(brother's age) - 12 = sister's age
x - 12 = 14
x - 12+12 = 14+12 ... add 12 to both sides to undo "minus 12"
x = 26
<h3>The brother is 26 years old</h3>
