You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14
y = -24x - 3y = 18 (use the substitution method)4x - 3y = 18 (substitute -2 for y, and solve for x))4x - 3(-2) = 184x + 6 = 18 (subtract 6 to both sides)4x = 12 (divide by 2 to both sides)x = 3Thus, (3, -2) is the solution of the given system of equations.
-2y = 10 2y = -10 y = -5
y=7+x =x=7-x
What are we solving here for, Z, X, or Y?If solve for Z then the answer would be z = x + yIf solve for X then the answer would be z = z - yIf solve for Y than the answer would y = z - xHope this help.
Does it say solve for y?
You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14
If: -11x+y = 13 Then: y = 11x+13 whereas 11 is the slope and 13 is the y intercept
11
If you mean: 11x+2y = 34 then y = -10.5x+17 whereas -10.5 is the slope and 17 is the y intercept of a straight line equation
U can subtract 18 from each side of the equation.
If: 11x-8y = 32 Then: -8y = -11x+32 And: y = 1.375x-4 in slope-intercept form
y + y + 2 = 182y + 2 = 182y = 16y = 8whew !
A: 11x = 5y + 80 B: 9x - 15y = 120 A: 11x - 5y = 80 B: 9x - 15y = 120 A: 11x - 5y = 80 B: 3x - 5y = 40 A - B: 8x = 40 x = 5 Now we can plug that value of x into one of the original equations to solve for y: 11(5) - 5y = 80 55 - 5y = 80 -5y = 25 y = -5
18+y=32 y=14
6x +108=18y y=6x/18+108/18 y=x/3+6
y2+7y=18 y2+7y-18=0 (y+9)(y-2)=0 y=-9 & y=2
