Updated: 4/28/2022

y = 3x

3x + 4y = 30

3x + 4(3x) = 30

3x + 12x = 30

15x = 30

x = 2

y = 3x

y = 3(2)

y = 6

Simplify the algebraic expression 7x squared minus 4y plus 3x squared plus 5y plus 2 and evaluate it for x equals 3 and y equals 9?

7(3y-2)-(-4y+9)

What equation is equivalent to 3x-4y equals 8?

3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2

What is equivalent to 3x-4y equals 8?

3x-4y = 8 -4y = -3x+8 y = 3/4x-2 or y = 0.75x-2 which is the equivalent in slope intercept form

The system of equations 3x-6y equals 20 and 2x-4y equals 3 is?

the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.

Is 3x plus 2y equals 15 and 6x plus 4y equals 30 Consistent or inconsistent?

We will see. 3X + 2Y = 15 6X + 4Y = 30 I do not like the look of elimination, so substitution 3X + 2Y = 15 3X = 15 - 2Y X = 5 - 2/3Y -------------- 6(5 - 2/3Y) + 4Y = 30 30 - 12/3Y = 30 30 - 4Y = 30 this is inconsistent in approach 3(5 - 2/3Y) + 2Y = 15 15 - 15/3Y = 15 another bad approach, try elimination to show inconsistency - 2(3X + 2Y = 15) 6X + 4Y + 30 -6X - 4Y = - 30 6X + 4Y = 30 I think it is safe to say these systems of equations are inconsistent --------------------
