Step-by-step explanation:
To graph a linear equation Y=3x means to draw a line in the 2-D plane. Notice that the intercept on y-axis is 0 meaning the line will pass through the origin and slope of line is 3. However, graphing this line is fairly straightforward. For every value of x in real number, Y is 3 times that value of x.

Answer:
Given -
x - y = -1 ------- case 1
3x + 2y = 12 ------ case 2
y = x + 1
put in case 2nd
3x + x+ 1 =12
x + 1 = 12 \4 + 1
= 4
1st case = x - 4 + 1
= x = -5
2nd case = 3x +2y = 12
x = 3 + 8 - 12
x = -1
hope it's helpful for you .
