Solve by substitution or elimination<br> 4X – 3y = 7<br> 4x + y = 11
Simora [160]

Answer:

(5/2 , 1)

Step-by-step explanation:

4X – 3y = 7

4x + y = 11

———————

Multiply a -1 to the bottom equation to get the 4x as a negative so it cancels out.

4x - 3y = 7

-4x - y = -11

——————

-4y = -4

Divide by -4

y = 1

Substitute the value of y into one of the equations and solve

4x - 3(1) = 7

4x -3 = 7

4x = 10

Divide by 4

X = 10/4

Simplify by dividing by 2

x = 5/2

Therefore the answer is (5/2, 1 )

the product of two consecutive integers n and n+1 is 42. what is the positive integer that satisfies the situation?
MrMuchimi
n(n+1)=42 \\&#10;n^2+n=42 \\&#10;n^2+n-42=0 \\ \\&#10;a=1 \\ b=1 \\ c=-42 \\ b^2-4ac=1^2-4 \times 1 \times (-42)=1+168=169 \\ \\&#10;n=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-1 \pm \sqrt{169}}{2 \times 1}=\frac{-1 \pm 13}{2} \\&#10;n=\frac{-1 -13}{2} \ \lor \ n=\frac{-1+13}{2} \\&#10;n=\frac{-14}{2} \ \lor \ n=\frac{12}{2} \\&#10;n=-7 \ \lor \ n=6

The positive integer is 6.
The consecutive integers are 6 and 7.
