4x-2y+3x+2y When simplified: 7x
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
4x-2y = 6 -7x+2y = -15 Add both equations together in order to eliminate y: -3x = -9 Divide both sides by -3 in order to find the value of x: x = 3 Substitute the value of x into the original equations to find the value of y: Solution: x = 3 and y = 3
(7x+2)(2y-1)
Subtract by 7x and divide by 2.
Manipulate such that y is the subject of the equation 7x - 2y = -14 2y = 7x +14 y = (7/2)x + 7
7x-2y = 14 -2y = -7x+14 y = 3.5x-7
-7x - 2y = -3
7x-2y=10 -2y=10-7x y=-5+(7/2)x y=(7/2)x-5 (Final answer)
-11/6
The standard form is 7x + 2y - 3 = 0
x = -3 y = -2
Im guessing that the equation is 7x - 2y +3z= 19 so the answer is 7x + 3z= 19
3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
Do you mean 7x+2y = 16 and 21x-6y = 24? If so then it is simultaneous equation with the solution being: x = 12/7 and y = 2
Write the equation of the line in the slope-intercept form, y = mx + b, where b is the y-intercept.7x + 2y = 28 (subtract 7x to both sides)7x - 7x + 2y = -7x + 282y = -7x + 28 (divide by 2 to both sides)y = -(7/2)x + 14Thus, the y-intercept is 14.Or7x + 2y = 28 (let x = 0 to find the corresponding y-value, which is the y-intercept)7(0) + 2y = 282y = 28 (divide by 2 to both sides)y = 14
