You subtract 11 from both sides and r equals negative 7. See...
r+11=3
-11 -11
r=7
a = 4
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
x + 3 = 11 (to solve for x, subtract 3 fromeach side of the equation) x + 3 - 3 = 11 - 3 (then simplify) x = 8 (this is the answer)
3+d=11 d would have to be the number added to 3 that results in the answer 11. I can think of one: 8. Are there any others?
m= -3
a = 4
2x+3 = -11 2x = -11-3 2x = -14 x = -7
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
-2 plus 5 equals +3
x + 3 = 11 (to solve for x, subtract 3 fromeach side of the equation) x + 3 - 3 = 11 - 3 (then simplify) x = 8 (this is the answer)
3
3+d=11 d would have to be the number added to 3 that results in the answer 11. I can think of one: 8. Are there any others?
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
it equals 28
m= -3
