Top Answer

You cannot solve one equation in two unknowns. The given equation defines a line in the 2-dimensional plane and every point on the line is a solution. There are, therefore, an infinite number of solutions.

00.75x = 30 Divide both sides by 0.75:- x = 40

45 = 30 + m Subtract 30 from both sides: 15 = m

We don't know what operation you want. 1 x 30 = 30 0 + 30 = 30 60 - 30 = 30 900/30 = 30

30p = 900 divide each side by 30 p = 30 ------------ and 30 * 30 = 900 0r 30^2 = 900

To solve this one, subtract 50 from 180 and you'll have your answer.

v is -15... -15*2 = -30... -30+11= -19.

5/6=x/30 150=6x 25=x

2/6=x/30 60=6x 10=x

Using algebra to solve this problem (12 + .25x = 30), the answer (x) is 72.

x2 + 13x = -30 ∴ x2 + 13x + 30 = 0 ∴ (x + 3)(x + 10) = 0 ∴ x ∈ {-3, -10}

11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3

n=3,y=4 2(n+3y)=30

x+30 = 3x-50 x-3x = -50-30 -2x = -80 x = 40

How do you solve 4y plus x equals 8

2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20

10 - 2n = 30 10 - 2n + 10 = 30 + 10 2n = 40 2n/2 = 40/2 n = 20

If you mean 7 times 4y then it is 28y If you mean 7x times 4y then it is 28xy

Not enough information to solve

8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3

13-3x = 43 -3x = 43-13 -3x = 30 x = -10

-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2

You can't solve a formula with no equals sign
