2-4 Math Test.

10t = 11

T = 11/10 Divide both sides of the equation by 10. Write as fraction.

a/8 = -6

a = -48 Multiply both sides of the equation by 8, reduce the numbers with the greatest common factor.

b/7 = 5

b = 35 Multiply both sides of the equation by 7 and reduce the numbers with the greatest common factor.

9b = 4

b = 4/9 divide both sides by 9.

{step one} -5= 1 = a

Move variable to the left-hand side and change its sign, move the constant to the right- hand side and change its sign. | -a=1 + 5

{step three} -5= 1 = a

Change the sign on both sides of the equation | a = -4

{step two} -5= 1 = a

calculate the sum. | -a = 4

-2x+3=-x + 12

x = -9 Move variable to the left and constant to the right, collect like terms then subtract the numbers change the signs on both sides of the equation

14=28+7x

x=-2 move the variable to the left and the constant to the right. Subtract, then divide by -7.

3(z-3)=9

z=6 divide both sides of the equation by 3, Move the constant to the right hand side and change its sign then add the numbers (This probably isn't the way you learned it, sorry)
