Question

Y + 3x =11
y-2x = 1
plsss helpp

Answer 1

Explanation:

Y + 3X = 11 Y - 2X = 1

Solve one equation for Y

Y - 2x = 1

Y = 1 + 2X

Substitute the Value of Y on the other equation

Y = 1 + 2X

1 + 2X + 3x = 11

1 + 5X = 11

Solve for X

5X = 10

X = 10/5

X = 2

Now Substitute X for 2in the first Equation

Y - (2 * X) = 1

Y- (2 * 2) = 1

Y - 4 = 1

Solve for Y

Y = 5

Answer

X = 2 and Y = 5 or in interval notation ( 2 , 5 )
