Answer:

x = 0

y = -3

Step-by-step explanation:

-5x + y = -3 --------------(I)

3x - 8y = 24 ------------(II)

Multiply the equation (I) by 8

(I)*8    - 40x + 8y = -24

(II)     <u>     3x -  8y   =  24</u><u> </u>   {Add and y will be eliminated}

           -37x          = 0

                     x     = 0

Plugin x = 0  in equation(I)

-5*0 + y = -3

     0 + y = -3

           y = -3

Answer:

- 5x + y =-3    ......1

3x -8y = 24.........2

eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3

-40 x +8 y =-24 ...........3

3 x   - 8y  = 24     ......... 2

·································

-37 x +0 = 0

··························

x =0

put x = 0 in equation 2

3 x -8 y =24

3×0 -8 y = 24

0 -8 y=24

-y =24÷8

-y =3

y = -3

ans ;

x = 0

y = -3

The product of a number and -7 amounts to seven times the sum of that number and 20. Find the number.
MA_775_DIABLO [31]

Answer: -10

Step-by-step explanation:

If you put it in an equation it would be -7x=7(x+20). You would then -7x to both sides to get -14x=140. Just divide -14 on both sides to isolate x. This equates to -10. If you put -10 back into the equation then it says that 70 is 7 times larger than 10. Which it is.
