-2 + 5 = x
same as:
5 - 2 = x
x = 3
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
15x minus 8=minus 180 3x+8=24

x = 25 / 3squared + 5
It is an equation with the plus or minus signs missing which makes it impossible to solve.
minus 5
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9

x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
15x minus 8=minus 180 3x+8=24
X=1
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 !!!!!
