5x + 2y = 7 . . . (1)
y = x + 1 . . . (2)
Putting (2) into (1) gives
5x + 2(x + 1) = 7 => 5x + 2x + 2 = 7 => 7x = 7 - 2 = 5 => x = 5/7
From (2) y = 5/7 + 1 = 12/7
Therefore, solution is {(5/7, 12/7)}
Answer:
504
Step-by-step explanation:80/100 multiplied by 630
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following equation:
We manipulate algebraically to write the equation of the slope-intersection form:
We check if the given point belongs to the equation:
The point does not belong to the equation.

N I G G E RStep-by-step explanation:
Okay so what you need to do is find the value of x or y. Substitute x or y for 0. After you do that, you'll be left with x on one side and y on the other. That's perfect. If x is alone, you want to substitute that into the equation, In parentheses. Then when you solve for the other term, you'll actually get a number answer. Then put that into the equation and substitute it where it should go, then solve and you'll get the second number
