x-y=11 how to salve it
Answers
Step-by-step explanation:
x + y = 11
- x - x
_______________
0 + y = 11 - x
y = -x + 11 ==> slope: m = -1 , y-intercept: b = 11
Thus, one solution to this equation is (0, 11). That is, y = 11 when x = 0.
For the next problem: 3x + 3y = 6 and 2x + y = 2
This is a system of linear

x + y = 11 ==> This is a linear equation in standard form, it is not a system. A system of equations consists of two or more equations.
You can rearrange the linear equation to put it in slope-intercept form, y = mx + b, where m is the slope of the line and b is the y-intercept (the y-intercept is where the line intercepts with the y-axis; in other words, it is what y is when x=0). To do so, subtract x from both sides of the equation:
x + y = 11
- x - x
_______________
0 + y = 11 - x
y = -x + 11 ==> slope: m = -1 , y-intercept: b =11
Answer:
x=11+y
y=11+x
Step-by-step explanation:
if we want to find x
then, take -y to RHS whe we take -y to RHS it becomes +y
If we want to find y then -x go to RHS then
-x becomes +x
