x=2 because 9-(14)=-5
Question 3C: Four minus seven equals negative two.
no it equals a positive
You can write this as two equations, and solve them separately. The two equations are:x - 19 = -3and:-x - 19 = -3
x=-1 ^ how do you know?
given: x - 4 = -y or, -y = x - 4 or, y = -(x - 4) or y = -x + 4 or y = 4 - x i.e. for x > 4, the equation x - 4 = -y is true.
x = 4 and y = 7
To solve the equation negative 51 equals k minus 34, you can rewrite it as -51 = k - 34. To isolate k, add 34 to both sides: -51 + 34 = k. This simplifies to k = -17. Thus, the solution is k = -17.
51 + 2z + 8z = 23 Collect 'like terms' 51 + 10z = 23 Subtract '51' from both sides 10z = 23 - 51 = -28 z = -28 /10 z = - 2.8 NB However, you have NOT indicated the mathematical signs !!!!!
15x minus 8=minus 180 3x+8=24
x = 4 and y = 7 which will satisfy both equations
3-(-9) Considering a negative plus a negative equals a positive your equation can be rewritten as 3+9 Which equals 12
It is an equation with the plus or minus signs missing which makes it impossible to solve.
Question 3C: Four minus seven equals negative two.
Without an "equals" word or sign somewhere, there is nothing to solve.You only have an expression, not an equation.
