y = 8
Actually, 2x + 3y + z is an expression, because it is a mathematical noun.
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
"3y + 4y = 19" is a mathematical sentence involving one unknown, y. If you wanted it solved (ie you meant to ask; "What is y in 3y plus 4 y equals 19"), then: 3y + 4y = 19 → (3 + 4)y = 19 → 7y = 19 → y = 19/7 = 2 5/7 ≈ 2.71
3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
The equation for 3y + 3y = -1 is 3y + 3y = -1.
y = 8
2x plus 3y is not an equation, it is an expression.
y = 8
-2x plus 3y equals 1
technically, you need to put in a second variable, x, at the end of the equation.
Actually, 2x + 3y + z is an expression, because it is a mathematical noun.
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
20+6y is the equation simplified, but there is no way to figure out the answer.
It's a simple linear equation in 'y'. If you'd like to know the value of 'y' that solves it, you can find it as follows: 3y - 5 = 19 Add 5 to each side: 3y = 24 Divide each side by 3 y = 8
Any equation of the form 2x + 3y = c, where c is a constant value, represents a line parallel to the given line 2x + 3y = 12.
Convert the equation to the standard slope intercept form of y = mx + c, where the value of m is the slope. -5x + 3y = 3 3y = 5x + 3 y = 5/3x + 1 Then the slope is 5/3.
