➷ Use the simultaneous equations method:

x - 4y = 6

3x + 4y = 10

Add these two equations together to cancel out 'y':

4x = 16

Divide both sides by 4:

x = 4

substitute this value into one of the equations:

(4) - 4y = 6

Subtract 4 from both sides:

- 4y = 2

Divide both sides by -4:

y = -0.5

Answer:

x = 4, y =1/2 is the solution of system of equations.

Step-by-step explanation:

We have given   the system of equations :

x - 4y = 6             (eq 1)

3x + 4y = 10         (eq 2)

We have to solve the system of equations.

Find the value of x from (eq 1)   we get,

x = 6+4y     (eq 3)

Put in eq 2 we get,

3(6+4y) + 4y = 10

18+12y +4y = 10

18 +16y = 10

16y =10-18

16y = -8

y = -1/2

Put y =-1/2 in  (eq 3) we get,

x = 6+4(-1/2)

x = 6 -2= 4.

x = 4, y =1/2 is the solution of system of equations.

Solve 80% of x = 100 or 0.8x = 100
suter [353]

Answer:

125

Step-by-step explanation:

divide both sides of the equation by 0.8

0.8÷0.8=0.8÷100

any expression divided by 1 is itself

x=100÷0.8

divide the numbers

100÷0.8=125

125 is your answer
