2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
-1-2x-4x=19-6x-1 = -19x = 3
3x-2 = 2x+3 3x-2x = 3+2 x = 5
-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
To solve this, present the equation in the standard slope/intercept form of y = mx + c. 'm' is the slope. 2x + 5y = 10 5y = -2x + 10 y = -2/5x + 2 Therefore, -2/5 is the slope.
what is the solution of x-5y=10 and 2x-10y=20
x=10 y=4
To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
(2x)ysquared
You cannot solve one equation in two unknowns.
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
This is already the equation. Now you just have to solve it. x=5.
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
A 2-step equation that equals 13 could be: 2x + 7 = 13. To solve this equation, first subtract 7 from both sides to isolate the variable: 2x = 6. Then, divide both sides by 2 to solve for x: x = 3. Therefore, when x = 3, the equation 2x + 7 equals 13.
-12
2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9
